The aim of the study was to study the results of treatment of patients with discolored teeth using various types of lumineers and composite veneers.Materials and methods. The study involved patients with discoloration of the teeth who underwent dental treatment: in group I (n = 10) – using lumineers made of ceranite ceramics, in group II (n = 10) – using modified lumineers made from lithium disilicate, in the group III (n = 20) – using composite veneers. The duration of follow-up after treatment was 24 months.Results. According to the results of a two-year observation, and analysis of the effectiveness of treatment using lumineers made of ceramite ceramics Lumineers by Cerinate (USA), using modified lumineers made of lithium disilicate IPS e.max Press (Liechtenstein) and using IPS Empress direct (Liechtenstein) composite veneers was higher in the group using lumineers compared to composite veneers, but these differences were not statistically significant. Also, there were no statistically significant differences when using lumineers made of ceranite ceramics and modified lumineers made of lithium disilicate.

Purpose To evaluate the effect of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography (OCT) in macular edema associated with various retinal vascular disorders. Methods This prospective nonrandomized clinical interventional study included 81 eyes (76 patients) comprised of Group I, 57 eyes (51 patients) with diabetic macular edema; Group II, 10 eyes (10 patients) with branch retinal vein occlusion; and Group III, 13 eyes (13 patients) with central retinal vein occlusion. All eyes received an intravitreal injection of 4 mg triamcinolone acetonide (with the solvent) in the operation theater under sterile conditions. Results Mean preinjection central macular thickness was 531.84±132 μm in Group I, 458.4±149 μm in Group II, and 750.81±148 μm in Group III. All groups showed a statistically significant decrease in mean central macular thickness at 1 month (300.7±119 μM in Group I, 218.2±99 μm in Group II, and 210.5 ±56 μm in Group III) and 3 months (253.19±109 μm in Group I, 187±47 μm in Group II, and 182±50 μm in Group III) after injection (p<0.05). Mean follow-up was 22±2.4 weeks. Mean visual acuity increased in all three groups (preoperative visual acuity in Group I, 1.2±0.4 logMAR units; Group II, 1.24±0.5 logMAR units; Group III, 1.1 ±0.4 logMAR units; 1 month postinjection in Group I, 0.88±0.3 logMAR units; Group II, 0.67±0.3 logMAR units; Group III, 0.86±0.4 logMAR units; 3 months postinjection in Group I, 0.84±0.4 logMAR units; Group II, 0.59±0.3 logMAR units; Group III, 0.82±0.5 logMAR units) (p<0.05). Forty-one eyes completed 6 months and 20 eyes completed 9 months follow-up. Twelve of 20 (41%) eyes in Group I, 2/6 (33%) eyes in Group II, 3/6 (50%) eyes in Group III, and 8/15 (53%) eyes in Group I, 1/3 (33%) eyes in Group II, and 2/2 (100%) eyes in Group III developed recurrence of macular edema with worsening of visual acuity at 6 and 9 months, respectively. Thirty-three (40.7%) eyes developed IOP elevation (at least one reading > 24 mmHg). One eye developed infective endophthalmitis. Conclusions Intravitreal injection of triamcinolone acetonide may be considered as an effective treatment for reducing macular thickening due to diffuse diabetic macular edema, venous occlusion associated macular edema, and may result in increase in visual acuity at least in the short term. Further follow-up and analysis is required to demonstrate its long-term efficacy.

Transsphenoidal microsurgery is the standard treatment for patients with Cushing’s disease. However, there is general lack of agreement regarding the definition of cure. We studied 58 patients with corrected hypercortisolism after transsphenoidal surgery for Cushing’s disease. Plasma and urinary cortisol levels were measured after surgery. After the postsurgical hypocortisolism stage (or periodically in patients without hypocortisolism), urinary free cortisol, plasma cortisol at 0800 h and 2300 h, morning cortisol after 1 mg dexamethasone, and cortisol response to insulin-induced hypoglycemia were performed. Patients were classified in 3 groups: group I, patients with transient hypocortisolism and normal hypothalamus-pituitary-adrenal axis afterwards; group II, patients with transient hypocortisolism and abnormalities in the circadian rhythm or the stress response afterwards; and group III, patients without postoperative hypocortisolism. Thirty-three patients were included in group I, 8 in group II, and 17 in group III. Groups I and II were similar in postsurgical plasma cortisol (46.9 ± 30.3 vs. 60.7 ± 38.6 nm) and mean follow-up (69.8 vs. 68.8 months) but were significantly different in their recurrence rate (3.4% vs. 50%, P &lt; 0.001). Patients in group III had normal postsurgical plasma and urinary cortisol but persistent abnormalities in circadian rhythm and stress response. After a mean follow-up of 39.1 months, their recurrence rate was similar to that of group II (64.7% vs. 50%). The complete normalization of the adrenocortical function, which is always preceded by postsurgical hypocortisolism, is associated with a very low recurrence risk and should be considered, in our opinion, the main criterion of surgical cure in Cushing’s disease.

Aim. To estimate the efficacy of invasive and non-invasive long-term ECG monitoring in comparison with conventional follow-up for the detection of silent atrial fibrillation (AF)/atrial flutter (AFL)/atrial tachycardia (AT) in patients with a cryptogenic stroke.Methods. The randomized, prospective, two-center study enrolled 36 patients who suffered cryptogenic stroke (CS) or transient ischemic attack (TIA) without past history of AF/AFL/AT. Patients were randomized in a 1:1:1 ratio to one of the three ECG monitoring strategies: standard arrhythmia monitoring (group I, n=12), ECG-monitoring with implantable loop recorder (group II, n=12), and ambulatory noninvasive ECG monitoring (group III, n=12). The primary endpoint was the time to the first detection of AF/AFL/AT. Patients, assigned to the group I, underwent an assessment at scheduled and unscheduled visits and received ambulatory ECG monitoring 28 days and 1 year after randomization. Patients in the group II underwent implantation of Reveal XT (Medtronic, USA) with the daily remote data transmission to CareLink Network. In the group III, for long-term external monitoring, Spyder system (WEB Biotechnology, Singapore) was used for up to 28 days.Results. During the first 28 days of observation, there were no significant differences in AF detection rates between groups I, II, and III: 0 (0%), 1 (8%), and 2 (17%) cases, respectively, р=0.537. During the year of observation, AF/AFL/AT episodes were detected in 1 case (8%) in the group I, 6 cases (50%) in the group II, and 2 cases (17%) in the group III, p=0.0486. The mean time from enrollment into the study to detection of the first AF/AFL/AT episode was 67 days (15; 97) in all groups. In the groups II and III, the first arrhythmia episodes were detected by monitoring devices on days 24 and 6, respectively. In most cases, arrhythmia episodes detected by long-term monitoring were asymptomatic. Recurrent stroke or TIA events occurred in group I and III (1 case in each group), but not in the group with implantable cardiac monitors. Subgroup analysis showed that significantly higher AF/AFL/AT detection rate was associated with stroke, CHA2DS2VASc score ≥2, and the presence of hypertension. For the 12 months of follow-up, the mean AF burden in the group II was 0.4 (0.2; 0.5) hours per day (1.6%). In the patients with recurrent stroke, AF burden was 3.2% compared to 0.9% in the rest of patients.Conclusion. Detection of silent AF with implantable cardiac monitors is superior to standard and long-term external monitoring in cryptogenic stroke patients.

Objective. To specify the role and indications for application of аpparatus of external fixation (АEF) in treatment of unstable pelvic osseous injuries (UPOI); to study up the advantages and faults of the external fixation method; to share the experience of treatment, using this procedure. Маterials and methods. There were 229 patients, suffering pelvic injuries, examined on the base of orthopedic-traumatological centre of Kyiv’s Regional Clinical Hospital in 2005 - 2017 yrs and distributed into three Groups. In Group I 143 (62.4%) injured persons were included, in whom external osteosynthesis played the function of temporary measures of fixation, in Group II - 27 (11.8%) patients, in whom while hospitalization a fracture was fixed, using AEF, аnd after stabilization of the state the posterior pelvis osteosynthesis and reposition was conducted, in Group III - 59 (25.8%) patients, who, using several indications, were definitely treated, applying the external fixation method only. Results. Excellent effect of treatment in Group I was registered in 23 (19.0%), a good one - in 58 (47.9%), satisfactory - in 32 (26.4%), poor - in 8 (6.6%) of 121 patients; in Group II - accordingly, - in 5 (20.8%), 11 (45.8%), 7 (29.2%) and 1 (4.2%) of 24 patients; in Group III - accordingly, in 4 (8.3%), 12 (25%), 23 (47.9%) and 9 (18.6%) of 48 patients. Conclusion. Best results of treatment of patients with unstable pelvic osseous injuries were obtained while applying the tactics of change from external fixation into internal one. On the first stage the pelvic ring fixation, using AEF, was performed, аnd after stabilization of a patient general status - internal osteosynthesis. Application of the internal osteosynthesis method permits to control and stabilize the reposition achieved, to conduct the sacro-ileal joint revision.

Background: Aim of this study was to evaluate the role of physical rehabilitation to improve the quality of life (QOL) of people after kidney transplantation. Patients and methods: Analyzes the results of treatment of 57 recipients (mean age 35±9,65 years) donor kidney at different times of the postoperative period. Depending on the physical rehabilitation program allocated 3 groups of patients: group II — physical rehabilitation was carried out only in the first week after surgery to prevent early postoperative complications, in group I — during the year; in group III combined 30 relatively healthy people do not need an organ transplant and with a mean age 33,7±8,7 years, leading a normal life, not engaged in regular recreational physical culture. Quality of life was assessed using a questionnaire SF36 at 1, 3, 6 and a 12 months after surgery. Results: One year after surgery in both groups compared with preoperative indicators marked improvement according to all scales of the questionnaire. However, in group I indicators of quality of life were higher than in group II from 11,4 to 19,7%, and even some items questionnaire SF-36 is higher than in group III which is associated with the physical rehabilitation. Conclusion: It has been shown that exercises is an important component of treatment and rehabilitation after kidney transplantation and help improve both the psychological and the physical component of quality of life.

Purpose. Evaluation of the visual and refractive results of additional correction using LASIK and PRK methods in patients with residual refractive error after previous cataract surgery. Patients and methods. The prospective open study included 57 patients (79 eyes) who previously underwent cataract phacoemulsification (n = 37) or refractive lensectomy (n = 42) with various IOL models implantation (2012–2017). The average age of patients was 50.8 ± 13.9 (19–79) years. Operations LASIK (91.1 %) and PRK (8.9 %) were carried out according to standard methods. In 6 cases, femtosecond laser supported by laser correction. The target refraction ranged from –0.25 to 0.25 D in most (97.5 %) cases. The follow-up period ranged from 6 to 9 months. Results. The patients were divided into groups according to the type of residual refractive error (Group 1 — myopia, group II — emmetropia and group III — hyperopia). Statistically significant differences were determined for the species of previously implanted IOLs — in group II, the frequency of monofocal IOLs was significantly higher (p < 0.05). In group II, the values of the cylindrical component of refraction were significantly higher compared with groups I and III (p < 0.05). In group I, a significant (p < 0.05) decrease in the spherical component of refraction from –1.36 ± 0.92 to –0.2 ± 0.8 D was observed. In patients of group II, there was a slight increase in the spherical component of refraction from 0 ± 0.20 to 0.25 ± 0.29 D (p > 0.05). In group III, a significant (p < 0.05) decrease was observed in the spherical component of refraction from 1.27 ± 0.69 to 0.43 ± 0.49 D. When analyzing the cylindrical component of refraction in group I, its decline was noted from –0.69 ± 0.5 to –0.38 ± 0.46 D (p > 0.05). In group II, the largest decrease in the cylindrical component was observed from –1.6 ± 1.0 to 0.03 ± 1.10 Dptr (p < 0.01). In all the studied groups, a statistically significant (p < 0.05) increase in UCFVA was revealed in the postoperative period. Indicators K1 and K2 did not significantly change. Conclusion. The high efficiency of the correction using the LASIK, PRK and femtoLASIK methods on pseudophakic eyes with the achievement of the target refraction in most of the studied cases was shown. This method can be used as an alternative to spectacle and contact correction in patients with residual refractive error after cataract phacoemulsification and refractive lensectomy with IOL implantation.

Abstract Allogeneic stem cell transplantation (ASCT) is an important curative modality for patients with acute myeloid leukemia (AML), but no large studies with mature followup after a uniform conditioning regimen and stem cell source have been reported. We previously published (Copelan EA. Blood; 78:838–43, 1992) the results of 127 patients with AML who underwent ASCT following preparation with oral busulfan (16 mg/kg) and cyclophosphamide (120mg/kg) (BuCy2) with a median follow-up of 3 years. We now present data on 316 AML patients, including the initial cohort, who underwent ASCT from 1984 to 1995 at 7 participating institutions the United States and Australia. All patients received bone marrow grafts from HLA-identical sibling donors following myeloablative preparation with BuCy2. One hundred fifty-seven patients were transplanted in first remission (CR1, group I), 49 in second remission (CR2, group II) and 110 patients were beyond CR2 or had refractory disease (group III). Cyclosporine or tacrolimus-based regimens were routinely administered to prevent graft-versus-host-disease (GVHD). Median follow-up of surviving patients exceeds 12 years (range 3 – 18 years). At the time of analysis 126 patients (40%) were alive. The estimated leukemia-free survival (LFS) for group I at 3 and 12 years is 63% (95% CI: 47 – 79%) and 49% (95% CI: 33 – 66%), for group II is 50% (95% CI 36 – 64%) and 33% (95% CI: 17 – 49%) and group III is 25% (95% CI: 17 – 32%) and 16% (95%CI: 8 – 24%) respectively. The estimated relapse rate for patients in group I at 3 and 12 years is 15% (95%CI: 9 – 21%) and 28% (95% CI: 20 – 36%), for group II is 38% (95% CI: 24 – 52%) and 48% (95% CI: 31 – 65%), and group III is 56% (95% CI: 4 – 68%) and 65% (95% CI: 53 – 77%). For the entire cohort (n=317), using multivariate analysis, younger age (p&lt;0.004) and transplantation in CR1 (p&lt;0.001) were predictive of long-term overall survival (OS) and LFS. Transplantation in CR1 (p&lt;0.001), and presence of chronic GVHD (p=0.003) were associated with decreased risk of relapse. One hundred forty-two patients were alive and free of leukemia at 3 years; of these patients, 75% are leukemia-free survivors at 12 years. Considering only these patients, the cumulative incidence of relapse beyond 3 years was 17% and the cumulative incidence of non-relapse mortality was 9%; only 2 patients died beyond 3 years from respiratory failure. For this group, none of the factors analyzed (including age, remission status at the time of transplantation or the presence of chronic GVHD) was predictive for OS, LFS or relapse. In conclusion, although most remissions in AML patients surviving leukemia-free for at least 3 years following ASCT are durable, late relapse occurs in 17%. One in four patients alive and free of leukemia at 3 years will relapse or die from NRM over the subsequent 9 years. Figure Figure

✓ Forty-six neonates with intracranial hemorrhage were classified into three groups on the basis of the major computerized tomography (CT) scan findings: Group I consisted of 24 cases of subarachnoid hemorrhage, Group II 20 cases of intracerebral and/or intraventricular hemorrhage, and Group III two cases of subdural hemorrhage. The initial scans in Group I showed blood in the interhemispheric fissure and the supratentorial recess. Sixty percent had an associated hypodensity in the frontal and/or parietal areas, thought to be an indication of ischemia. Changes in the configuration of the ventricular system were infrequent. Initial scans in Group II showed hematomas as follows: one in the brain stem, five in the basal ganglia, 10 in the temporal lobes, and 11 in the ventricles. In 70% of these cases, changes in the configuration of the ventricular system were seen, including compression of a lateral ventricle by mass effect, ventricular dilatation with blood, and obstructive hydrocephalus. Subarachnoid blood was an associated finding in 55% of cases, and focal and diffuse cerebral edema in 40%. Scans in both Group III patients initially showed a mass effect from a subdural clot. In all, 30 patients had one or more follow-up CT scans, and 13 of these were scanned at regular intervals. None of the Group I patients developed hydrocephalus, but 85% of Group II patients with intraventricular blood extending from an intracerebral hemorrhage had this complication. A seizure disorder occurred in 31% of Group I patients and 20% of Group II patients, where it was seen exclusively in those with an intralobar hematoma. A major motor disturbance occurred in 16% of patients; their CT scans showed evidence of brain destruction involving enlargement of a lateral ventricle, porencephaly, or focal atrophy. Computerized tomography is a useful adjunct to the diagnosis, management, and follow-up study of neonatal intracranial hemorrhage, and correlates well with the clinical findings.

The aim of the study was to detect neurological abnormalities in human immunodeficiency virus (HIV) infected children. This was achieved by a prospective evaluation, from November/1995 to April/2000, of 43 HIV infected children (group I) and 40 HIV seroreverters children (group II) through neurological exam and neurodevelopmental tests: Denver Developmental Screening Test (DDST) and Clinical Adaptive Test / Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS). A control group (III), of 67 children, were evaluated by CAT/CLAMS. Hyperactivity, irritability and hypotonia were the findings on neurological examination, without statistical differences between group I and II. On CAT/CLAMS, the group I developmental quotient (DQ) was significantly lower than the other groups. The same occurred in DDST, with group I presenting significantly more failures than group II. Nineteen HIV children of group I had brain computed tomographic scan, with abnormalities in three of them (basal ganglia calcification, white matter hypodensity and asymmetry of lateral ventricles). We conclude that in HIV infected children a neurodevelopment delay occur early in the disease, and it can be detected by screening tests.

Purpose Patients with localized, grossly resected, or gross residual (orbital only) embryonal rhabdomyosarcoma (ERMS) had 5-year failure-free survival (FFS) rates of 83% and overall survival rates of 95% on Intergroup Rhabdomyosarcoma Study Group (IRSG) protocols III/IV. IRSG D9602 protocol (1997 to 2004) objectives were to decrease toxicity in similar patients by reducing radiotherapy (RT) doses and eliminating cyclophosphamide for the lowest-risk patients. Patients and Methods Subgroup A patients (lowest risk, with ERMS, stage 1 group I/IIA, stage 1 group III orbit, stage 2 group I) received vincristine plus dactinomycin (VA). Subgroup B patients (ERMS, stage 1 group IIB/C, stage I group III nonorbit, stage 2 group II, stage 3 group I/II) received VA plus cyclophosphamide. Patients in group II/III received RT. Compared with IRS-IV, doses were reduced from 41.4 to 36 Gy for stage 1 group IIA patients and from 50 or 59 to 45 Gy for group III orbit patients. Results Estimated 5-year FFS rates were 89% (95% CI, 84% to 92%) for subgroup A patients (n = 264) and 85% (95% CI, 74%, 91%) for subgroup B patients (n = 78); median follow-up: 5.1 years. Estimated 5-year FFS rates were 81% (95% CI, 68% to 90%) for patients with stage 1 group IIA tumors (n = 62) and 86% (95% CI, 76% to 92%) for patients with group III orbit tumors (n = 77). Conclusion Five-year FFS and OS rates were similar to those observed in comparable IRS-III patients, including patients receiving reduced RT doses, but were lower than in comparable IRS-IV patients receiving VA plus cyclophosphamide. Five-year FFS rates were similar among subgroups A and B patients.
