The healing of venous and arterial ulcers is slow, and in some cases, they may not heal at all. This study aims to demonstrate the clinical advantage of Nevelia®, an innovative collagen dermal template substitute (DS) in venous and arterial chronic ulcers treatment. 35 patients affected by chronic vascular ulcers with a mean area of 35.1 ± 31.8 cm2 were treated with DS followed by autologous dermal epidermal graft (DEG). Follow-up was performed at 7-14-21 and 28 days after DS implant and 7-14-21 and 28 days after DEG. At 28 days after DEG, the mean values of Manchester Scar Scale was of 1.8 ± 0.7 for skin color, 1.6 ± 0.7 for skin contour, 1.7 ± 0.7 for distortion, and 1.7 ± 0.7 for skin texture, whereas skin was matte in 27 patients (77%) and shiny in the remaining eight cases (23%). Histological findings correlate with the clinical result showing a regenerated skin with reactive epidermal hyperplasia and dermal granulation tissue after two weeks (T1), and after three weeks (T2) a re-epithelialization and a formed new tissue architecture analogue to normal skin physiology. These data suggest that Nevelia® could be useful to treat chronic venous and arterial ulcers.

Abstract Background There are limited data on the effects of blood pressure (BP) control and lipid lowering in secondary prevention of coronary artery disease (CAD) patients. We report a secondary analysis of the effects of BP control and lipid management in participants of the HIJ-CREATE, a prospective randomized trial. Methods HIJ-CREATE was a multicenter, prospective, randomized, controlled trial that compared the effects of candesartan-based therapy with those of non-ARB-based standard therapy on major adverse cardiac events (MACE; a composite of cardiovascular death, non-fatal myocardial infarction, unstable angina, heart failure, stroke, and other cardiovascular events requiring hospitalization) in 2,049 hypertensive patients with angiographically documented CAD. In both groups, titration of antihypertensive agents was performed to reach the target BP of <130/85 mmHg. The primary endpoint was the time to first MACE. Incidence of endpoint events in addition to biochemistry tests and office BP was determined during the scheduled 6, 12, 24, 36, 48, and 60-month visits. Achieved systolic BP and LDL-Cholesterol (LDL-C) level were defined as the mean values of these measurements in patients who did not develop MACEs and as the mean values of them prior to MACEs in those who developed MACEs during follow-up. Results During a median follow-up of 4.2 years (follow-up rate of 99.6%), the primary outcome occurred in 304 patients (30.3%). Among HIJ-CREATE participants, 905 (44.2%) were prescribed statins on enrollment. Kaplan–Meier curves for the primary outcome revealed that there was no relationship between statin therapy and MACEs in hypertensive patients with CAD. The original HIJ-CREATE population was divided into 9 groups based on equal tertiles based on mean achieved BP and LDL-C during follow-up. For the analysis of subgroups, estimates of relative risk and the associated 95% CIs were generated with a Cox proportional-hazards model (Figure 1). The relation between LDL cholesterol level and hazard ratios for MACEs was nonlinear, with a significant increase of MACEs only in the patients with inadequate controlled LDL-C level even in the patients with tightly controlled BP. Conclusions The results of the post-hoc analysis of the HIJ-CREATE suggest that clinicians should pay careful attention to conduct comprehensive management of lipid lowering even in the contemporary BP lowering for the secondary prevention in hypertensive patients with CAD.

Objective: The main objective of this study is to evaluate the availability of lateral antebrachial cutaneous nerve (LACN) autograft for acute or delayed repair of segmented digital nerve injuries. Patients and Methods: 13 digital nerve defects of 11 patients; treated with interposition of LACN graft that harvested from ipsilateral extremity were included in the study. Mean follow up period was 35, 7 months. The mean time from injury to grafting is 53, 3 days. The results of the mean 2PDT and SWMT values of injured /uninjured finger at the end of follow up period were evaluated with Paired T test. The correlation between the defect length and the difference of 2PDT, SWMT values between the uninjured and injured finger at the end of follow up period; were evaluated with Pearson - correlation analysis. Results: The mean value of our 2PDT and SWMT results are ~5,923, ~3, 52, respectively in which can be interpreted between the normal and diminished light touch. The defect length and difference percentage of SWMT values is positively and significantly correlated statistically. Mean length of interposed nerve grafts was 18.5 mm. The age of the patient and the mean values of 2PDT and SWMT with the difference % of 2PDT and % of SWMT are not statistically correlated. Conclusion: Based on results regarding sensory regaining at recipient side and negligible sensory deficit at harvesting side, we suggest that lateral antebrachial cutaneous nerve might be a valuable graft option for digital nerve defects.

Abstract Background and aims: Proline hydroxylation is essential for collagen synthesis in wound healing. Therefore, hydroxyproline quantification may be a suitable marker of wound healing in diabetic tissue. Material and method: This is a prospective casecontrol clinical study including 90 referral patients from our clinics in Golestan hospital affiliated to Jundishapour Medical University, Ahwaz-Iran, during a period of 18 months. Three groups were recruited: intervening diabetics with non-ischemic foot ulcers, diabetics without foot ulcers (normal diabetics) and non-diabetics without foot ulcers (normal non-diabetics) as control groups (n=30 per group). 500 mg of granulation tissue from ulcers after treatment and 500 mg of normal skin from both control groups were taken for the measurement of hydroxyproline levels. Results: 13 (43.3%) males and 17 (56.7%) females in trial group were analysed. There was no significant differences in age, gender, and BMI between groups. Mean hydroxyproline concentration in wound granulation tissue (140.44 μg/g) was statistically different from the mean concentration in the skin content of normal diabetics (173.22 g/g,) and the skin content of nondiabetics (178.83 μg/g) (p=0.001). There were no statistically significant differences between the mean values of normal diabetics and non-diabetics (p=0.63). Conclusion: Our results showed the presence of a lower quantity of hydroxyproline in diabetic patients with foot ulcers compared to control groups. This raises the issue of its effectiveness in delaying the repair process in diabetics. Therefore, compensating for tissue hydroxyproline deficit can be a clue in improving diabetic tissue repair.

Purpose The purpose of this study was to evaluate the effect of correction of abnormal radiographic parameters on postoperative pain in a group of patients treated arthroscopically for femoracetabular impingement (FAI). Methods A retrospective study was performed on 23 patients affected by mixed-type FAI and treated arthroscopically. There were 11 males and 12 females with a mean age of 46.5 (range: 28–67) years. Center-edge (CE) and α angles were measured on preoperative and postoperative radiographic and magnetic resonance imaging (MRI) studies and were correlated with persistent pain at follow-up. Results The mean preoperative CE and α angles were 38.6 ± 5.2 and 67.3 ± 7.2 degrees, respectively. At follow-up, in the 17 pain-free patients, the mean pre- and postoperative CE angle were 38.1 ± 5.6 and 32.6 ± 4.8 degrees, respectively, whereas the mean pre- and postoperative α angles at MRI were 66.3 ± 7.9 and 47.9 ± 8.9 degrees, respectively. In six patients with persistent hip pain, the mean pre- and postoperative CE angles were 39.8 ± 3.6 and 35.8 ± 3.1 degrees, respectively, whereas the mean pre- and postoperative α angles were 70.0 ± 3.9 and 58.8 ± 2.6 degrees, respectively. Mean values of all the analyzed radiological parameters, except CE angle in patients with pain, improved significantly after surgery. On comparing patient groups, significantly lower postoperative α angles and lower CE angle were observed in patients without pain. Conclusion In case of persistent pain after arthroscopic treatment of FAI, a new set of imaging studies must be performed because pain may be related to an insufficient correction of preoperative radiographic abnormalities. Level of Evidence Level IV, retrospective case series.

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.

Background. Facial threading is a common tradition in Taiwan, Southeast Asia (called “Bande Abru”), Middle East (called “Khite”), and Egypt (called “Fatlah”). In addition to the ability to remove facial vellus hairs, facial threading can make the skin fairer and shinier. However, there has been a lack of hard evidence regarding the effects of facial threading on the skin. Objective. To examine the effects of facial threading on skin physiology as well as visual and touch senses by using scientific instruments. Methods. A total of 80 participants were allocated to receive facial threading, application of powder only, exfoliation, and shaving. Prior to and following the assigned treatment, a noninvasive skin condition detection device was used to measure skin coarseness, hydration, melanin, and erythema index. Sense assessment and image analysis were also performed. Results. This study showed that facial threading was found to improve the facial skin roughness indices with significant decreases by 30.4%, 35.9%, and 16.7%, respectively, for the participants’ forehead, cheek, and mouth corner skin. No significant adverse changes in moisture levels and skin pigment indices were detected. In addition, there was improvement in subjects’ touch sense of their skin and feelings about skin color. Conclusions. Traditional facial threading can remove facial vellus hairs and lower skin roughness levels, thereby improving the skin texture. However, pricking sensation appeared during the facial threading process, which might cause concerns about irritation.

Arthrocentesis in temporomandibular joint disorders can be associated with the intra-articular infiltration of various drugs with the objective of increase treatment efficacy. The aim of this study was to evaluate the clinical indexes variation in patients affected by temporomandibular joint disorders treated with arthrocentesis and sodium hyaluronate (SH) injections. A total of 28 patients suffering from temporomandibular joint disorders underwent one cycle of five arthrocentesis and infiltrations of sodium hyaluronate. Spontaneous mouth opening improved from 36.3 ± 7.5 mm to 45.1 ± 1.9 mm at six months follow-up. A significant reduction in the pain at rest and during mastication mean values emerged at follow-up (p < 0.0001). The mean masticatory efficiency, evaluated through a visual analogic scale, showed improvement at the follow-up period, highlighted by the increase of mean value from a baseline of 3.1 ± 1.2 to a mean value of 8.5 ± 1.2 (p < 0.0001). The mean severity of the joint damage at baseline time was 2.4 ± 0.9 and decreased to 0.4 ± 0.3 at the end of the follow-up period. The decrease in values is confirmed by statistical test (p < 0.05). Our data show how arthrocentesis integrated with sodium hyaluronate infiltrations performed under local anesthesia is a valid method of treating temporomandibular joint disorders.

ABSTRACT Objective: Evaluation of the results of the use of VEPTR (Vertical Expandable Prosthetic Titanium Rib - Synthes Spine Co.(r), West Chester, Pennsylvania, USA) as an option in spinal instrumentation without fusion in younger children with scoliosis, considering the complications inherent to spinal fusion in this age group. Methods: Sixteen (16) patients with scoliosis, regardless of etiology, with a mean age of 5.2 (3-8) years, were followed up by Spine Surgery Group at Hospital Getúlio Vargas, Recite-PE, and were submitted to surgical correction of the deformity using VEPTR, from April/2009 to July/2014. The survey was conducted through medical register review, and photographic and radiographic records, with the measurement of pre- and postoperative curves by the Cobb method. Results: The mean values of Cobb angle in the preoperative period, in the immediate postoperative period and after the last distraction were, respectively, 84.1° (112°-60°), 55.4° (92°-16°) and 64.4° (100°-16°), with an average initial correction of 28.7° (34.1%) and final correction of 19.7° (23.4%). The mean follow-up was 23.1 (0-61) months with an average distraction of 3.1 (0-8). The complication rate in this study was 62.5%. Conclusion: The VEPTR presented considerable correction rates of scoliosis curves in patients whose age contraindicate the spinal fusion methods. It is necessary to improve the technique and the implant itself in order to reduce complication rates, which can be considered relatively high, in addition to the conduction of more studies with longer follow-up to determine the actual efficacy of the implant and the maintenance of long-term correction.

Abstract Context Discordant growth hormone (GH) and insulin-like growth factor-1 (IGF-1) values are frequent in acromegaly. Objective To evaluate the impact of different GH cutoffs on discordance rate. To investigate whether the mean of consecutive GH measurements impacts discordance rate when matched to the last available IGF-1 value. Design Retrospective study. Setting Referral center for pituitary diseases. Patients Ninety acromegaly patients with at least 3 consecutive evaluations for GH and IGF-1 using the same assay in the same laboratory (median follow-up 13 years). Interventions Multimodal treatment of acromegaly. Main Outcome Measures Single fasting GH (GHf) and IGF-1 (IGF-1f). Mean of 3 GH measurements (GHm), collected during consecutive routine patients’ evaluations. Results At last evaluation GHf values were 1.99 ± 2.79 µg/L and age-adjusted IGF-1f was 0.86 ± 0.44 × upper limit of normality (mean ± SD). The discordance rate using GHf was 52.2% (cutoff 1 µg/L) and 35.6% (cutoff 2.5 µg/L) (P = 0.025). “High GH” discordance was more common for GHf &lt;1.0 µg/L, while “high IGF-1” was predominant for GHf &lt;2.5 µg/L (P &lt; 0.0001). Using GHm mitigated the impact of GH cutoffs on discordance (GHm &lt;1.0 µg/L: 43.3%; GHm &lt;2.5 µg/L: 38.9%; P = 0.265). At receiver-operator characteristic curve (ROC) analysis, both GHf and GHm were poor predictors of IGF-1f normalization (area under the curve [AUC] = 0.611 and AUC = 0.645, respectively). The prevalence of disease-related comorbidities did not significantly differ between controlled, discordant, and active disease patients. Discussion GH/IGF-1 discordance strongly depends on GH cutoffs. The use of GHm lessen the impact of GH cutoffs. Measurement of fasting GH levels (both GHf and GHm) is a poor predictor of IGF-1f normalization in our cohort.

Background. The article has explored the problem of the humoral immunity recovery of elderly patients with chronic generalized periodontitis. Such immunological indicators as the immunoglobulin concentrations were used as detectors of inflammatory-destructive disease. Polyoxidonium has been suggested as an immunomodulator, as it promotes faster immune and clinical recovery compared to the conventional treatment regimens. Goals To assess the dynamics of clinical indicators and indicators of humoral immunity (sIgA, IgA, IgG and IgM levels), depending on immunomodulation, is added to the combined treatment regimen of elderly patients with periodontitis. Methods. Two patient cohorts of 69 elderly persons with chronic generalized periodontitis were examined. The conventional treatment was administered in both patient groups. The patients in the second cohort, along with other medications, received Polyoxidonium. The examination included gingival fluid and venous blood sampling, estimation of sIgA, IgA, IgG and IgM concentration as well as evaluation of PMA and SBI indices reduction. Results. The study has revealed the rise of IgG and IgM in venous blood. The recovery trend was observed in both cohorts, with a more marked dynamics in the second one. The mean values of antibodies concentration in the 2-nd group (since the 14th day) were statistically significant compared to the similar measures in the 1st one. After 3 months follow-up the substantial growth of immunoglobulins concentration was registered in the 1st cohort, whereas the 2nd one still showed the recovery trend. Results. The study has revealed the rise of IgG and IgM in venous blood. The recovery trend was observed in both cohorts, with a more marked dynamics in the second one. The mean values of antibodies concentration in the 2-nd group (since the 14th day) were statistically significant compared to the similar measures in the 1st one. After 3 months follow-up the substantial growth of immunoglobulins concentration was registered in the 1st cohort, whereas the 2nd one still showed the recovery trend. Conclusions. The inclusion of immunomodulator Polyoxidonium into the conventional treatment protocol of periodontitis promotes the immunologic reactivity recovery of elderly patients and the improvement of the therapeutic intervention effectiveness over the longer term.
