6069 Background: To evaluate the clinical and patologic results of surgical treatment of children born after Chernobyl and to compare these findings with well-known data of the group of patients who were children at the time of Chernobyl. To compare the clinical and pathologic features of thyroid cancer of children born after the Chernobyl versus those born prior to 1986. Methods: Comparison of clinical and pathologic result of surgical treatment of 141 patients born after Chernobyl (Group 1) and 589 patients (Group 2) aged 0–18 at the time of the disaster (1986) among the single institution clinical cohort within years 1995–2005. Results: In Group 1 there were 31 cancers (22%) vs. 243 (41%) in Group 2 (p<0.05 between Group 1 and Group 2). The rate of extrathyroid invasion was 69% vs. 36% (p<0.05 between Group 1 and Group 2). In Group 1, 17/21(80%) patients with extrathyroid invasion were found to have regional neck metastases (8 unilateral, 9 bilateral).The mean age in this subgroup was 13.4 ± 2.11 years but in the “benign subgroup” of Group 1 the mean age is 16.2 ± 0.77 years.In Group 2, 49/88 (55%) patients with extrathyroid invasion only had regional metastases. The mean age in this subgroup is 31.1 ± 4.7 years (p<0.05 between Group 1 and Group 2). We found cancer multifocality in 1 patient (3%, Group 1) vs. 55 (23%, Group 2).There were 19 cases (13.5%) of atypical adenomas in Group 1 vs. 46 (8%) in Group 2 (p<0.05 between Group 1 and Group 2). Histological types: solid follicular variant of papillary carcinoma (typical for radiation-induced children carcinomas with short latency) was found in 3 cases in Group 1 (9.5%) vs. 76 (31%) in the Group 2 (p<0.05 between Group 1 and Group 2). There was only one case of follicular thyroid cancer in Group 1 (3%) vs. 9% in Group 2. We did not find any relationship of cases of cancer in Group 1 to the Chernobyl-polluted area (only 3 patients − 10% from the nearest to Chernobyl regions) vs. 192 patients (80%) in Group 2 (p<0.05 between Group 1 and Group 2). Among patients with tumors of uncertain malignant potential 9 patients (6%) were from Chernobyl-polluted area vs.72% in Group 2 (p<0.05 between Group 1 and Group 2). Conclusions: Our data demonstrates higher likelihood of aggressive well-differentiated thyroid cancer among a pediatric population independently from Chernobyl irradiation and connected with another etiological factors of genesis of tumor.The solid-follicular variant of papillary cancer and multifocality are typical for radiation-induced carcinoma in children. No significant financial relationships to disclose.

Purpose. To evaluate the efficacy and safety of femtolaser-assisted phacoemulsification in glaucomatous eyes in the long-term follow-up. Materials and methods. A retrospective analysis of the results of the surgical treatment of patients with combined cataract and glaucoma pathology was analyzed. The patients were divided into groups depending on the method of surgical intervention: 1) phacoemulsification with femtolaser support (26 eyes, 23 patients); 2) phacoemulsification (36 eyes, 30 patients); Results. Before surgery, there were no statistically significant differences in IOP and corneal hysteresis (СН) between groups 1 and 2. The mean values of IOP cc, IOP g and СН of group 1 before surgery were 22.7±6.1 mm Hg, 20.9±6.9 mm Hg, 8.5±1.6 mm Hg; 2 group – 22.9±8.7 mm Hg, 21.6±8.9 mm Hg, 8.9±1.6 mm Hg respectively. Average values of IOP cc, IOP g and CН 5 years after the surgical treatment in group 1 were 15.3±1.2 mm Hg, 14.4±3.4 mm Hg, 9.6±4.2 mm Hg; in group 2 – 18.0±4.2 mm Hg, 16.1±4.2 mm Hg, 8.8±2.2 mm Hg respectively. In both groups, stabilization of IOP and CH indices was noted, which remained throughout the entire observation period, which shows the normalization of the biomechanical properties of the corneoscleral membrane of the eye in the long-term postoperative period. Conclusion. Femtolaser accompaniment of phacoemulsification is an effective and safe method of cataract surgery for combined pathology. Key words: femtolaser, cataract, glaucoma, phacoemulsification.

Abstract Objectives Influence of lymphatic metastases presence at immediate and follow-up results of pts surgical treatment is controversial especially for sporadic medullary thyroid carcinoma (SMTC). Methods 3330 thyroid cancer pts were operated on (1973-2009), among them—226 (6.8%) medullary thyroid cancer (MTC) patients. In 11 observations MTC was appeared as a part of MEN syndrome. Sporadic character of disease was confirmed in 215 (95.1%) cases. There were 140 (80.8%) females and 33 (19.2%) males (4.2:1.0) with average age 48.6 ± 2.7. Long-term results (1-40 years) were investigated in 173 (94.2%) cases. All SMTC patients were divided into 3 groups. Group 1 made of 80 (46.2%) T1- 3N0M0, Group 2 made of 47 (27.3%) T1-3N1a-bM0, 3 Group made of 46 (26.6%) T4N1a-bM0 patients. Results: Group 1 Organ-sparing operations were carried out in 59 (73.7%), thyroidectomies—in 21 (26.3%) patients. Multicentric tumor growth (MTG) was observed in 19.1%: in T1 cases—5.7%, T2—20.5%, T3—46.7%. All patients were undergone ipsilateral prophylactic central neck dissection (CND). Average period of postoperative observation (APPO) made 12.0 ± 1.7. 5 years survival rate made 98.4%, 10—91.7%. Local relapse of MTC was found in 1 patients (in contralateral thyroid lobe). Group 2 Organ-sparing operations were carried out in 20 (42.6%), thyroidectomies—27 (57.4%) with curative central or central and lateral lymphadenectomy (LAE). MTG took place in 47.2%. 6 group metastases only (T1a) were found in 38.9% and CND was performed. In other cases (61.1%) CND, lateral and mediastinal (8.3%) LAE were performed. APPO correspondent to 10.8 + 2.1 years. Repeated LAE because lymphatic metastases were carry out in 15 (31.9%) patients through 7.2 ± 2.4 years in average after initial operations. Tumor relapses were not found in thyroid remnant. 5 years survival rate made 89.2%, 10—67.8%. Group 3 MTG was observed in 64.3%. Central compartment group lymphatic metastases were revealed in 93.3%, in 2 to 5 groups — 86.7%, in mediastinum—38.5%, distant metastases—in 22.0%. Combined operations were performed in 58.9%, palliative—in 45 (26.6%) cases. Operations were completed by Tracheostomy in 38.4%. Adjuvant therapy (X-ray, chemotherapy) was applied in 28.9%. Postoperative lethality made 6.5%. APPO corresponded to 3.3 ± 0.8 (1-10 years). During first year, 8 patients have dead. 5 years survival rate made 32.4%. Conclusion Detection of regional metastases of SMTC during the first patients presentation significantly worsen survival rate. Early diagnose of SMTC by calcitonin level detection is the best way to improve results of treatment. Organ-sparing thyroidectomies with mandatory ipsilateral prophylactics CND are justified only at T1N0M0 sporadic MTC.

Abstract Background The prevalence of chronotropic incompetence (CI) in heart failure (HF) population is high and negatively impacts prognosis. In HF patients with an implanted cardiac resynchronisation therapy (CRT) device and severe CI, the effect of rate adaptive pacing on patient outcomes is unclear. Closed loop stimulation (CLS) based on cardiac impedance measurement may be an optimal method of heart rate adaptation according to metabolic need in HF patients with severe CI. Purpose This is the first study evaluating the effect of CLS on the established prognostic parameters assessed by the cardio-pulmonary exercise (CPX) testing and on quality of life (QoL) of the patients. Methods A randomised, controlled, double-blind and crossover pilot study has been performed in CRT patients with severe CI defined as the inability to achieve 70% of the age-predicted maximum heart rate (APMHR). After baseline assessment, patients were randomised to either DDD-CLS pacing (group 1) or DDD pacing at 40 bpm (group 2) for a 1-month period, followed by crossover for another month. At baseline and at 1- and 2-month follow-ups, a CPX was performed and QoL was assessed using the EQ-5D-5L questionnaire. The main endpoints were the effect of CLS on ventilatory efficiency (VE) slope (evaluated by an independent CPX expert), the responder rate defined as an improvement (decrease) of the VE slope by at least 5%, percentage of maximal predicted heart rate reserve (HRR) achieved, and QoL. Results Of the 36 patients enrolled in the study, 20 fulfilled the criterion for severe CI and entered the study follow-up (mean age 68.9±7.4 years, 70% men, LVEF=41.8±9.3%, 40%/60% NYHA class II/III). Full baseline and follow-up datasets were obtained in 17 patients. The mean VE slope and HRR at baseline were 34.4±4.4 and 49.6±23.8%, respectively, in group 1 (n=7) and 34.5±12.2 and 54.2±16.1% in group 2 (n=10). After completing the 2-month CPX, the mean difference between DDD-CLS and DDD-40 modes was −2.4±8.3 (group 1) and −1.2±3.5 (group 2) for VE slope, and 17.1±15.5% (group 1) and 8.7±18.8% (group 2) for HRR. Altogether, VE slope improved by −1.8±2.95 (p=0.31) in DDD-CLS versus DDD-40, and HRR improved by 12.9±8.8% (p=0.01). The VE slope decreased by ≥5% in 47% of patients (“responders to CLS”). The mean difference in the QoL between DDD-CLS and DDD-40 was 0.16±0.25 in group 1 and −0.01±0.05 in group 2, resulting in an overall increase by 0.08±0.08 in the DDD-CLS mode (p=0.13). Conclusion First results of the evaluation of the effectiveness of CLS in CRT patients with severe CI revealed that CLS generated an overall positive effect on well-established surrogate parameters for prognosis. About one half of the patients showed CLS response in terms of improved VE slope. In addition, CLS improved quality of life. Further clinical research is needed to identify predictors that can increase the responder rate and to confirm improvement in clinical outcomes.

Many parameters included in the Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) and CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke, vascular disease, age 65-74 years, sex category) scores also predict coronary artery disease (CAD). We modified the ATRIA score (ATRIA-HSV) by adding hyperlipidemia, smoking, and vascular disease and also male sex instead of female. We evaluated whether the CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, and ATRIA-HSV scores predict severe CAD. Consecutive patients with coronary angiography were prospectively included. A ≥50% stenosis in ≥1epicardial coronary artery (CA) was defined as severe CAD. Patient with normal CA (n = 210) were defined as group 1, with <50% CA stenosis (n = 178) as group 2, and with ≥50% stenosis (n = 297) as group 3. The mean ATRIA, ATRIA-HSV, CHA2DS2-VASc, and CHA2DS2VASc-HS scores increased from group 1 to group 3. A correlation was found between the Synergy between PCI with Taxus and Cardiac Surgery score and ATRIA ( r = 0.570), ATRIA-HSV ( r = 0.614), CHA2DS2-VASc ( r = 0.428), and CHA2DS2-VASc-HS ( r = 0.500) scores ( Ps < .005). Pairwise comparisons of receiver operating characteristics curves showed that ATRIA-HSV (>3 area under curve [AUC]: 0.874) and ATRIA (>3, AUC: 0.854) have a better performance than CHA2DS2-VASc (>1, AUC: 0.746) and CHA2DS2-VASc-HS (>2, AUC: 0.769). In conclusion, the ATRIA and ATRIA-HSV scores are simple and may be useful to predict severe CAD.

Objectives: To compare nasal and upper airway dimensions in patients with cleft lip and palate (CLP) who underwent nasoalveolar molding (NAM) with those without NAM during infancy using acoustic pharyngometry and rhinometry. Materials and Methods: Eccovision acoustic pharyngometry and rhinometry (Sleep Group Solutions) was used for assessment of mean area and volume of nasal and upper airway in patients with complete unilateral CLP (age range 16-21 years) treated with NAM (group 1, n = 19) versus without NAM (group 2, n = 22). Results: The mean nasal cross-sectional areas and volume were higher in group 1 compared to group 2 on both cleft ( P value <.001) and noncleft side ( P value >.05). The mean area and volume of upper airway were also significantly higher in group 1 compared to group 2 ( P value <.05). Conclusions: Nasoalveolar molding being one of the first interventions in chronology of treatment of patients with CLP, its long-term outcome on nasal and upper airway patency needs to be ascertained. The results of the present study show that the patients with CLP who have undergone NAM during infancy have better improvement in nasal and upper airway patency compared with those who had not undergone NAM procedure. The basic advantages of being noninvasive, nonionizing and providing dynamic assessment of nasal and upper airway patency make acoustic pharyngometry and rhinometry a diagnostic tool of choice to be used in patients with CLP.

Background: Fractures of the mandible can be studied and described in anatomic terms, functional considerations, treatment strategies, and outcome measures. The performance of any fixation system depends on multiple factors including plate adaptation, screw placement, bone quality, drilling conditions, and postoperative patient compliance. Bite force assesses masticatory muscle function under clinical and experimental conditions. Method: 30 patients with isolated, noncomminuted mandibular fractures were randomly divided into two equal groups. Group 1 patients were treated using 3-dimensional locking miniplates and group 2 patients were treated with standard miniplates. The bite forces were recorded at definite time intervals: preoperatively, and second week, sixth week, third month, and sixth month postoperatively. Result: At 6 weeks postoperative, 3 month postoperative, and 6 month postoperative, the mean bite force was found to be significantly higher among group 1 patients as compared to those in group 2 in all the sites. While at 2 week postoperative, the mean bite force was found to be significantly higher in Group 2 as compared to Group 1 at incisor region. Conclusion: The overall results of the present study show better performance in bite force for the 3-dimensional locking miniplate when compared with standard miniplates.

Background: Knot-tying suture-bridge (SB) rotator cuff repair may compromise the vascularity of the repaired tendon, causing tendon strangulation and medial repair failure. The knotless SB repair technique has been proposed to overcome this possibility and decrease retear rates. Purpose: To compare clinical and structural outcomes and retear patterns between the knot-tying and knotless SB techniques. We hypothesized that the knotless technique would result in lower retear rates owing to the preservation of intratendinous vascularity. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 104 patients with full-thickness rotator cuff tears were randomly and prospectively allocated to undergo knot-tying (group 1) or knotless (group 2) SB repair. Clinical outcome measures included range of motion, the visual analog scale (VAS) for pain, and the Constant score for function. Repair integrity was evaluated on magnetic resonance imaging scans using the Sugaya classification. Retears were also classified according to their pattern as type 1 (lateral) or type 2 (medial). Results: Overall, 88 patients (group 1: n = 42 [mean ± SD age, 54.3 ± 9.8 years]; group 2: n = 46 [mean ± SD age, 55.8 ± 8.2 years]) were included in the final analysis. The mean ± SD follow-up period was 25.4 ± 8.3 and 23.3 ± 7.2 months for groups 1 and 2, respectively. From preoperatively to postoperatively, the mean VAS pain score improved significantly in both groups (group 1: from 7.4 ± 1.7 to 1.0 ± 1.7; group 2: from 7.1 ± 1.9 to 1.3 ± 2.0; P < .0001 for both), as did the mean ± SD Constant score (group 1: from 51.7 ± 13.4 to 86.0 ± 11.5; group 2: from 49.4 ± 18.4 to 87.2 ± 14.8; P < .0001 for both). There was no significant difference between the groups for the postoperative VAS or Constant score. The retear rate was not significantly different between the groups (19.0% [8/42] in group 1 and 28.3% [13/46] in group 2; P > .05). There was a significant difference in the type 2 failure rate (75.0% [6/8] in group 1 and 23.1% [3/13] in group 2; P = .03). Conclusion: Both techniques showed excellent improvement and comparable clinical outcomes, and there was no significant difference in retear rates. Consistent with previously published data, the type 2 failure rate was significantly higher with the knot-tying technique. Registration: NCT03982108 ( ClinicalTrials.gov identifier).

Object This study addresses the changes in brain oxygenation, cerebrovascular reactivity, and cerebral neurochemistry in patients following decompressive craniectomy for the control of elevated intracranial pressure (ICP) after severe traumatic brain injury (TBI). Methods Sixteen consecutive patients with isolated TBI and elevated ICP, who were refractory to maximal medical therapy, underwent decompressive craniectomy over a 1-year period. Thirteen patients were male and 3 were female. The mean age of the patients was 38 years and the median Glasgow Coma Scale score on admission was 5. Results Six months following TBI, 11 patients had a poor outcome (Group 1, Glasgow Outcome Scale [GOS] Score 1–3), whereas the remaining 5 patients had a favorable outcome (Group 2, GOS Score 4 or 5). Decompressive craniectomy resulted in a significant reduction (p < 0.001) in the mean ICP and cerebrovascular pressure reactivity index to autoregulatory values (< 0.3) in both groups of patients. There was a significant improvement in brain tissue oxygenation (PbtO2) in Group 2 patients from 3 to 17 mm Hg and an 85% reduction in episodes of cerebral ischemia. In addition, the durations of abnormal PbtO2 and biochemical indices were significantly reduced in Group 2 patients after decompressive craniectomy, but there was no improvement in the biochemical indices in Group 1 patients despite surgery. Conclusions Decompressive craniectomy, when used appropriately in protocol-driven intensive care regimens for the treatment of recalcitrant elevated ICP, is associated with a return of abnormal metabolic parameters to normal values in patients with eventually favorable outcomes.

OBJECTIVE: To test the ability of a 5HT2a/c (trazodone) antagonist, to improve depression and motor function in Parkinson' disease (PD). METHOD: Twenty PD patients with and without depression were randomly assigned to receive trazodone (group 1) or not (group 2). They were evaluated through UPDRS and Hamilton Depression Rating Scale (HAM-D). RESULTS: For the UPDRS the mean score of group 2 was 33.1 ± 19.7 and 37.1 ± 18.0 at the end. For the group 1, the corresponding scores were 31.4 ± 11.3 and 25.9 ± 13.7. The variations in the Mann-Whitney test were 0.734 at the initial moment and 0.208 at the final moment. The variation in the comparison of the initial moment with the final moment was 0.005 providing statistical significance. For the HAM-D, the mean score went up 4 points in group 2, contrary to a 5.5 points decrease in group 1. CONCLUSION: Data analysis shows that this agent significantly improves depression, but the motor function improved only in the depressed patients. Because of the known anti-dopaminergic property of the 5-HT2c receptors, a possible approach for depression in PD could be the use of 5-HT2c antagonists, similarly to the use of atypical neuroleptics in case of psychotic symptoms.
