Objective. To study potentialities of posterior instrumentation for treatment of TB spondylitis in adults. Material and Methods. Data on the treatment outcomes of 93 adult patients with TB spondylitis at T2–L5, which underwent radical reconstructing and restorative surgeries in the period of active inflammatory process were analyzed. In 40 cases a traditional technique was used (Group 1); in 11 cases this technique was supplemented by posterior fixation with Harrington rods or CITO-plates (Group 2) and in 42 – with CDI (Group 3). Deformity dynamics, character of complications, and changes in neural disorders and pain dynamics defined the operative effect. Results. The absence of instrumented fixation in Group 1 was accompanied with the most significant decrease in graft sizes and most numerous complications in a zone of anterior fusion. Both these characteristics have least values in Group 3. Use of conventionally semi-rigid constructs in Group 2 caused 7 complications in a zone of posterior fixation out of 11 cases (66.4 %). There were 2 complications out of 42 cases (4.3 %) in Group 3. Short-term pain intensity decrease was achieved in all groups. However augmenting of pain syndrome was registered in a considerable number of patients in Groups 1 and 2 in a long-term period, while there were no negative long-term outcomes in Group 3. Conclusion. Combination of radical spinal reconstruction and fixation with segmented instrumentation of the third generation for TB spondylitis provides considerable improvement of treatment results and reduction of rehabilitation and in-hospital periods.

Abstract OBJECTIVES Chronic kidney disease (CKD) is prevalent in patients undergoing cardiovascular surgery, and it negatively impacts procedural outcomes; however, its influence on the outcomes of aortic surgery has not been well studied. This study aims to elucidate the importance of CKD on the outcomes of aortic root replacement (ARR). METHODS Patients who underwent ARR between 2005 and 2019 were retrospectively reviewed (n = 882). Patients were divided into 3 groups based on the Kidney Disease: Improving Global Outcomes criteria: Group 1 [estimated glomerular filtration rate (eGFR) ≥ 60 ml/min/1.73 m2, n = 421); Group 2 (eGFR = 30–59 ml/min/1.73 m2, n = 424); and Group 3 (eGFR < 30 ml/min/1.73 m2, n = 37). To reduce potential confounding, a propensity score matching was also performed between Group 1 and the combined group of Group 2 and Group 3. The primary end point was 10-year survival. Secondary end points were in-hospital mortality and perioperative morbidity. RESULTS Severe CKD patients presented with more advanced overall chronic and acute illnesses. Kaplan–Meier analysis showed a significant correlation between CKD stage and 10-year survival (log-rank P < 0.001). The number of events for Group 1 was 15, Group 2 was 49 and Group 3 was 11 in 10 years. Group 3 had significantly higher in-hospital mortality (13.5% vs 3.5% in Group 2 vs 0.7% in Group 1, P < 0.001) and stroke (8.1% vs 7.1% vs 1.2%, P < 0.001) as well as introduction to new dialysis (27.0% vs 5.4% vs 1.7%, P < 0.001). eGFR was shown to be an independent predictor of mortality (hazard ratio, 0.98; 95% confidence interval, 0.96–0.99). Comparison between propensity matched groups showed similar postoperative outcomes, and eGFR was still identified as a predictor of mortality (hazard ratio, 0.97; 95% confidence interval, 0.95–0.99). CONCLUSIONS Higher stage in CKD negatively impacts the long-term survival in patients who are undergoing ARR.

Abstract Background Although regional techniques have been suggested more in order to provide postoperative analgesia in inguinal hernia repairs, the ideal method is still controversial. The aim of this study was to evaluate the effect of preemptive transversus abdominis plane (TAP) block, local anesthetic infiltration (LAI) and intravenous dexketoprofen (IVD) on postoperative pain in inguinal hernia repairs. Methods This prospective study included 120 patients with American Society of Anesthesiologists status 1-3 between 18-75 years of age who undergoing elective inguinal hernia surgery under spinal anesthesia. The patients were allocated into three groups: USG-guided TAP block (Group 1, n = 40), USG-guided LAI (Group 2, n = 40) and IVD (Group 3, n = 40) before surgical incision. The mean of tramadol consumption, number of patients in requiring rescue analgesics, duration of postoperative analgesia and complications were recorded for 24 hours postoperatively. VAS scores were evaluated at the 30 minute, 1, 2, 4, 8, 12, 16 and 24th hours. Results There was no significant difference between the postoperative mean tramadol consumption [Group 1: 22.5 mg; Group 2: 20 mg; Group 3: 27.5 (p 0.833)]. The number of patients requiring rescue analgesics was statistically similar (p 0.787). VAS scores at 30. min, 1, 2, 4, 8 and 12 hours were statistically lower in Group 1 than in the other groups (p 0.003, 007, 0013, 0049, 0015, 0021). VAS scores at 30. min and 2. h were lower in Group 1 than Group 2 (p 0.049, 0.037). İn addition, VAS scores at 30 min, 1, 2, 8 and 12 hours were lower in Group 1 than in Group 3 (p 0.003, 0.006, 0.021, 0.017, 0.016). VAS scores at all hours were statistically similar between Group 2 and Group 3. Conclusion This study demonsrated that preemptive transversus abdominis plane block, local anesthetic infiltration or iv dexketoprofen for postoperative analgesia in inguinal hernia repairs had similar effects on postoperative tramadol consumption and number of requiring rescue analgesic patients. However, TAP block provides lower VAS values and excellent analgesia in more patients in the first 24 hours postoperatively.

Due to the growing number of patients with age-related diseases, the aim of the study was to investigate in the changes of aging rate (AR) in patients with comorbid course of arterial hypertension (H), type 2 diabetes mellitus (T2DM) and subclinical hypothyroidism (SH) and to study the features of these changes depending on hormonal imbalance. 118 patients (63 women and 55 men, average age — 53.6±4.3 years) were divided into 3 groups: group 1 (n=37) with isolated H; group 2 (n=42) — with H and T2DM; group 3 (n=39) — with H, T2DM and SH. The investigation program included: measurement of anthropometric parameters (blood pressure, height, body weight (BW), body mass index (BMI)), carbohydrate and thyroid metabolism using standard methods, biological age (BA) by V.P. Voitenko et al. Statistical processing was performed using the Statistica for Windows 8.0 software package. When evaluating AR, physiological aging was found in 8 patients (21.6%) of group 1, in 4 (9.5%) patients of group 2 and 3 (7.7%) of patients in group 3. In the overwhelming majority of the examined patients, premature aging (PA) was noted, however, the acceleration of PA between patients of groups 2 and 3 was not differ significantly (p>0.05). The increase in AR in group 2 patients was accompanied by an increase in BA by 7.2 years, in 3 group patients — by 7.3 years compared with their chronological age. A correlation analysis revealed a positive relationship between BMI and coefficient of aging rate (CAR) (r=0.679; p<0.05); BMI and BA (r=0.562; p<0.05) and CAR and the TSH level (r=0.050; p=0.388) in the 3rd group. Thus, the presence of hypertension and comorbid endocrinopathies — T2DM and SH significantly increases the AR and when assessing the effect of endocrine disorders, the presence of T2DM is more important than SH.

Background: It is usual to face clinical complexity in piles patients. They usually present with variable number of pile masses and in different grades of progression. This led to the idea of offering concomitant single stage management in our hemorrhoid patients matching to our criteria. We conducted hospital based descriptive study among the patients coming to my clinical practice falling in grade-1-3.Methods: All the patients falling in grade-1-3 and matching to our criteria were included. The study was conducted   from January 2012 to December 2020. Place of study was basically at two centres: Karamdeep medical centre, Kanpur and Mayo health care, Mohali. Total number of patients were 581. Patients having grade-4 piles and with local co-morbidities were excluded from the study. Modalities of treatment used were sclerotherapy, band ligation and hemorrhoidectomy.Results: Patients managed were divided into four groups – group 1 included patients with piles in grade-1; group-2 included patients having piles in grade-1 and 2; group-3 included patients having piles in grade-1 and 3; and group-4 included patients having piles in grade-1, 2 and 3. Total 952 pile masses were treated in 581 patients. Sclerotherapy was required in 732 (77%) masses, banding in 99 (10.3%) masses and surgery in 122 (12.7%) masses.Conclusions: Concomitant treatment policy proved to be comprehensive way to tackle pile patients of grade-1-3. Mixed and matched method using surgical and non-surgical modalities in a single sitting proved to be beneficial. 86.4% cases were cured this way. Cost of the treatment was economical with lesser complications including local mutilation and better quality of life.

Introduction: Preserved function of collecting duct is essential for the response to tolvaptan (TLV), and urinary level of aquaporin 2 (U-AQP2) can be a marker for vasopressin-dependent activity of collecting duct. Hypothesis: Higher levels of U-AQP2 in proportion to plasma levels of vasopressin (P-AVP) may be associated with better initial responses to TLV and eventually result in the improved prognosis after long-term treatment of TLV. Methods: Consecutive 60 in-hospital patients with stage D heart failure (HF) who received TLV on a de novo basis were enrolled during 2011-2013. We also selected 60 HF patients by propensity score matching who were hospitalized during the same period but never treated with TLV. Events were defined as death and/or HF re-hospitalization. Results: TLV (3.75-15 mg/day) was continuously administered except death or ventricular assist device implantation occurred. There were 41 patients (group 1) who had increases in UV over the first 24 h after TLV initiation, and all of them had U-AQP2/P-AVP ≥0.5 х103 with higher U-AQP2 levels (5.42 ± 3.54 ng/mL) before TLV treatment. On the other hand, UV rather decreased even after TLV initiation in 19 patients over the first 24 h (group 2). Those in the group 2 universally had U-AQP2/P-AVP <0.5 х103, extremely low U-AQP2 levels (0.76 ± 0.59 ng/mL, p<0.001 vs. group 1), and similar P-AVP with the group 1 at baseline. The 41 and 19 patients without TLV treatment (group 3 and 4) were respectively matched to the group 1 and 2 by propensity scores. Interestingly, every patient in the group 3 had U-AQP2/P-AVP ≥0.5 х103, and vice versa in the group 4. Among the four groups, congestion-related symptoms were only improved in the group 1 after 1 month of enrollment. The patients in the group 1 had significantly better event-free survival over 2-year by TLV treatment compared with the group 3 (76% vs. 43%, p<0.014). In contrast, the patients in the group 2 and 4 had very poor prognoses regardless of TLV treatment (7% vs. 11%, p=0.823). Conclusions: U-AQP2/P-AVP is a novel predictor for the initial response to TLV in HF patients. Patients with higher U-AQP2/P-AVP may enjoy a better prognosis by long-term TLV treatment probably due to efficient resolution of congestion.

ObjectiveIndividuals with primary adrenal insufficiency (PAI) or congenital adrenal hyperplasia (CAH) receive life-long glucocorticoid (GC) replacement therapy. Current daily GC doses are still higher than the reported adrenal cortisol production rate. This GC excess could result in long-term morbidities such as osteoporosis. No prospective trials have investigated the long-term effect of GC dose changes in PAI and CAH patients.MethodsThis is a prospective and longitudinal study including 57 subjects with PAI (42 women) and 33 with CAH (21 women). Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry at baseline and after 2 years. Subjects were divided into three groups (similar baseline characteristics) depending on changes in daily hydrocortisone equivalent dose (group 1: unchanged 25.2±8.2 mg (mean±s.d., n=50); group 2: increased 18.7±10.3 to 25.9±12.0 mg (n=13); group 3: decreased 30.8±8.5 to 21.4±7.2 mg (n=27)).ResultsSubjects in group 1 showed normal lumbar and femoral Z-scores which were unchanged over time. Group 2 subjects showed a significant decrease in femoral neck Z-scores over time (−0.15±1.1 to −0.37±1.0 (P<0.05)), whereas group 3 subjects showed a significant increase in lumbar spine and hip Z-scores (L1–L4: −0.93±1.2 to –0.65±1.5 (P<0.05); total hip: −0.40±1.0 to −0.28±1.0 (P<0.05)). No changes in BMI over time were seen within any group. Reduction in GC dose did not increase the risk of adrenal crisis.ConclusionThis study demonstrates for the first time that cautious reduction in hydrocortisone equivalent doses leads to increases in BMD, whereas dose increments reduced BMD. These data emphasize the need for the lowest possible GC replacement dose in AI patients to maintain health and avoid long-term adverse effects.

Abstract Background Isolated tricuspid surgery has markedly higher mortality rates (9–10%) in contemporary national registries compared to other single-valve operations. The optimal timing and indications remain controversial, and earlier surgery before developing ESC guidelines class 1 indications may improve the survival for isolated severe tricuspid regurgitation. Purpose We aimed to compare the characteristics and outcomes of isolated tricuspid regurgitation (TR) surgery by indication. Methods Consecutive patients undergoing isolated tricuspid valve surgery for TR without other concomitant valve surgery at Cleveland Clinic from 2004 to 2019 were studied. Indications were divided into group 1: ESC guidelines class 1 (severe symptomatic TR), group 2: infective endocarditis, and group 3: non-class 1 (asymptomatic severe TR with or without right ventricular dilation and/or dysfunction) and no endocarditis, for comparative analyses of characteristics and outcomes. Results The study included 207 patients (group 1: 115, group 2: 48 and group 3: 44) with mean age 54.1±17.8 years, 116 (56.0% females and 151. Tricuspid repair was performed in 72.9% (73.0%, 66.7% and 79.5% for Groups 1–3, P=0.381). Group 3 patients were younger, had higher prevalence of primary TR, lower prevalence of heart failure, atrial fibrillation, chronic lung disease, cirrhosis, renal impairment, right ventricular and left ventricular dysfunction than Group 1. Overall operative mortality rates were 4.9% ( group 1: 7.0%, group 2: 4.2% and group 3: 0.0%), while mortality during follow-up of 3.3±4.0 years was lower for group 3 than for groups 1 or 2 (Figure 1). Independent predictors of long-term mortality were Group 1 compared to Group 3 and reduced estimated glomerular filtration rate. Conclusion Patients without class I or endocarditis indications had superior unadjusted and adjusted survival compared to those with these indications. The high mortality rate of isolated TR surgery may be reduced by both earlier surgery and being performed at an experienced cardiac surgery center. Figure 1.

Autologous serum eyedrops (ASE) are effective in treating various ocular surface diseases, including damages induced by long-term use of preserved glaucoma eyedrops. However, there has been no study on whether ASE is effective without stopping the causative eyedrops. This retrospective observational study included 55 patients with ocular-surface diseases caused by long-term use of preserved glaucoma eyedrops: 18 patients who used ASEs for 2 months without discontinuing the use of glaucoma eyedrops (Group 1), 22 patients who used ASEs for 2 months, discontinuing the use of glaucoma eyedrops for the first month (Group 2) and 15 patients who used non-preservative artificial tears for 2 months, discontinuing the use of glaucoma eyedrops for the first month (Group 3). There were no intergroup differences in the baseline values of the Schirmer I test results, tear breakup time (TBUT), ocular surface staining (OSS) score, loss of the meibomian gland, meibum quality and ocular-surface disease index (OSDI). Group 1 showed significant differences in TBUT, OSS score and OSDI at 2 months when compared to the baseline values before treatment, while Group 2 showed significant differences in those values at both 1 and 2 months. There were no differences in any of the parameters at baseline, 1 month or 2 months in Group 3. Our result suggested that ASE is effective for treating ocular surface diseases caused by glaucoma eyedrops containing preservatives and its effects can be expected without interruption of glaucoma eyedrop treatment.

Abstract Abstract 4885 Introduction: Fludarabine has been reported to increase the incidence of relapse and histological transformation in chronic lymphocytic leukemia (Thornton PD, Leukemia research, 2005) and Waldenstrom macroglobulinemia (Leleu X, J Clincal Oncology, 2009). The purpose of our study was to investigate the role of Fludarabine and the risk of transformation and relapse in follicular lymphoma (FL). Patients and Methods: This is a retrospective single institution study. We included 50 patients consecutively diagnosed with FL Grade I and II based on WHO classification of lymphoid malignancies. Grade III patients were excluded from the study. Median follow up is 2.86 years. Patients were grouped according to the initial therapy chosen by their treating physicians: Group 1(n=14) included patients on observation and radiation therapy, Group 2 (n=6) included patients on Fludarabine based regimens, Group 3(n=13) included CVP-R and other rituximab regimens and Group 4(n=17) included R-CHOP. Data collected included time to the onset of biopsy proven transformation, time to relapse, mortality and overall survival. Level of significance was set at <0.05. Results: Median age of the patients was 56.5 and it was not significantly different for the various groups. High risk FLIPI score was seen in 66% of patients treated with Fludarabine regimens as compared to 61% of R-CHOP treated patients. Overall, relapse occurred in 38% patients and transformation occurred in 16% patients during the follow up period. Fludarabine treated patients had the highest relapse rate: 50% (p=0.03). R-CHOP group has lowest relapse rate: 11%. Transformation rate was highest in the Fludarabine group: 33%, as compared to 13% to 17% in other groups (p=0.10). Mortality rate was 7% in group 1, 16% in group 2, 23% for group 3 and 5% in group 4 (p=0.44). Time to relapse/progression in group 1 was 2.9 years; in group 2 was 2.1 years; in group 3 was 2.7 years and in group 4 was 5.8 years. Conclusions: In our study, Fludarabine treated patients appear to be at higher risk for relapse and transformation compared to patients treated with R-CHOP. The differences can not be explained on the basis of known prognostic factors such as age or FLIPI score. The retrospective nature of the study and the small numbers of patients preclude more definitive conclusions. Further research is needed with large number of patients. Disclosures: No relevant conflicts of interest to declare.

ABSTRACT Objective:  To compare the postretention stability of maxillary incisors alignment in subjects with Class I and II malocclusion treated with or without extractions. Materials and Methods:  The sample comprised 103 subjects with initial maxillary anterior irregularity greater than 3 mm and was divided into four groups: group 1 comprised 19 patients with Class I malocclusion treated with nonextraction (mean initial age = 13.06 years); group 2 comprised 19 patients with Class II malocclusion treated with nonextraction (mean initial age = 12.54 years); group 3 comprised 30 patients with Class I malocclusion treated with extractions (mean initial age = 13.16 years); group 4 comprised 35 patients with Class II malocclusion treated with extractions (mean initial age = 12.99 years). Dental casts were obtained at three different stages: pretreatment (T1), posttreatment (T2), and long-term posttreatment (T3). Maxillary incisor irregularity and arch dimensions were evaluated. Intergroup comparisons were performed by one-way analysis of variance followed by Tukey tests. Results:  In the long-term posttreatment period, relapse of maxillary crowding and arch dimensions was similar in all groups. Conclusion:  Changes in maxillary anterior alignment in Class I and Class II malocclusions treated with nonextractions and with extractions were similar in the long-term posttreatment period.
