Objective The present study was performed to evaluate the effect of different bone cement distributions along the fracture line on clinical and imaging outcomes of vertebral augmentation. Methods In total, 84 patients who underwent vertebral augmentation for a single osteoporotic vertebral compression fracture from January 2016 to August 2018 were retrospectively reviewed. These patients were divided into two groups according to the relationship between the bone cement distribution and the fracture line: the unilateral group (n = 23) and the bilateral group (n = 61). Postoperative clinical and imaging parameters were compared between the two groups. Results Statistical analyses showed no significant difference in postoperative pain relief, bone cement leakage, nerve injury, or new vertebral fracture between the two groups. Significant recovery from vertebral compression was observed in the bilateral group after surgery, but there was no significant difference in vertebral compression after surgery in the unilateral group. Conclusions Pain relief was similar for different types of cement distributions along the fracture line, but a bilateral cement distribution exhibited better recovery from vertebral compression and did not increase bone cement leakage in the vertebral augmentation procedure.

Introduction: Evidences suggest that different subgroups of idiopathic clubfoot exist with differences in severity and treatment outcomes. This study compares the severity and treatment outcomes of unilateral and bilateral clubfoot. Material and methods: We retrospectively studied 161 patients (bilateral 66, unilateral 95) with primary idiopathic clubfeet to evaluate the differences in severity and treatment. The parameters analyzed were precasting Pirani score, number of casts required, pretenotomy Pirani score, pretenotomy dorsiflexion, rate of tenotomy, and post-tenotomy dorsiflexion achieved. A Pirani score of at least 5 was classified as very severe and 4.5 or less was classified as less severe. Results: There were 49=(74.24%) male and 17 (25.75%) female patients in the bilateral group and 76 (80%) male and 19 (20%) female patients in the unilateral group. Out of 95 unilateral patients, 34 were left sided (35.8%). Comparing severity, the mean precasting Pirani score in bilateral patients (5.4 ± 0.6) was statistically more than the unilateral patients (4.9 ± 0.7). The number of casts required was significantly more in bilateral feet compared to unilateral (bilateral 5.3 ± 1.7, unilateral 4.7 ± 1.7; p < 0.011). Achilles tenotomy was required in all feet. Post Ponseti treatment, the foot deformity correction achieved (pretenotomy Pirani score, pretenotomy, and post-tenotomy dorsiflexion) was statistically similar in both unilateral and bilateral feet. Conclusions: Idiopathic bilateral clubfoot was more severe than unilateral foot at initial presentation and required more number of corrective casts. Post Ponseti treatment, the deformity correction in bilateral foot was similar to unilateral foot.

The purpose of this study was to investigate the effects of a multimodal exercise program (MEP) on the functional capacity of patients with Parkinson's disease (PD) according to disease severity and gender. Fourteen patients with PD participated in the study and were distributed into groups according to 1) stage of disease and 2) gender. Functional capacity was evaluated before and after 6 months of intervention. The overall PD patient group improved their coordination and strength. Men and women improved in strength performance after exercise. Men also improved on coordination. For severity of disease, the unilateral group improved in strength, while the bilateral group improved in strength, balance, coordination and the UPDRS-functional score. In conclusion, a MEP is efficient in improving components of functional capacity in patients with PD, especially in strength. Gender may be considered in the exercise program. Individuals in the bilateral disease group appeared to benefit more from exercise.

SynopsisSex differences in minor psychiatric morbidity (MPM) have been investigated among three aboriginal groups in Taiwan. The study included both ethnographic observation and a sample survey (N = 733) using a modified Clinical Interview Schedule. The findings lend support to the hypothesis that although a female excess of MPM will be found among the patrilineal group (the Bunun), the reverse will be observed in the matrilineal group (the Ami); no such difference will be found in the bilateral group (the Atayal). Further analysis revealed sex differences in the mean duration of MPM and similar incidence ratios between two sexes in these three groups. Possible sociocultural explanations are proposed.

Background: Gold standard treatment for chronic anal fissure is lateral internal sphincterotomy (LIS) which is usually performed at a single location. This randomized study compares bilateral to unilateral lateral internal sphincterotomy.Methods: Patients were randomized into two equal groups (64 each) to undergo either bilateral (Group A) or unilateral (Group B) open lateral internal sphincterotomy (LIS). Comparative study was done in terms of symptomatic relief of pain, incontinence, complete healing of fissure, and recurrence. Chi-square test was used as a test of significance.Results: Both groups had comparable demographic and clinical characteristics. Mean operative time for was longer for bilateral LIS (P-value <0.05). Mean pain score (VAS) in bilateral LIS group was lower in early post-operative period (P-value <0.05). At the end of 4th week 65.6% of patients in bilateral LIS group and 56.25% of patients in unilateral LIS group had completely healed fissures (P-value <0.05). Mean Wexner score for incontinence was comparable, while significant decrease in resting anal pressure was noted at 1 month in BLIS group. There was one recurrence in unilateral LIS group.Conclusions: Bilateral LIS resulted in better outcome in terms of early pain relief, early reduction of anal pressures, complete healing rate in 4 weeks with no recurrence. It does not increase the risk of incontinence and has better patients’ satisfaction as compared to unilateral LIS.

Abstract Amblyopia is the interocular visual acuity difference of two lines or more with best correction in both eyes. Ocular occlusion therapy depends on neuroplasticity, and thus is effective in children but not in adult with later diagnoses. Transcranial Direct Current Stimulation (tDCS) is suggested to increase neuroplasticity. To determine if combined therapy of bilateral tDCS and ocular occlusion improves visual function in adults with amblyopia, we conducted a double blind randomized, controlled pilot trial in volunteers with amblyopia (ClinicalTrials.gov Identifier: NCT05016830). While applying ocular occlusion and performing a reading task, participants received sham bilateral tDCS or bilateral tDCS. Visual function and visual evoked potential were evaluated immediately after. 12 volunteers with amblyopia were randomized, 2 were excluded after misdiagnosis confirmation. A significant increase in visual acuity was observed after stimulation in the bilateral group (n = 5) versus the sham group (n = 5) along with a significant increase in visual evoked potentials amplitude in the amblyopic eye response. No significant changes were observed in stereopsis and contrast sensitivity. No volunteer reported any harm derived from the intervention. Our results suggest that bilateral tDCS might improve visual acuity in amblyopic adults through increasing neuroplasticity, which allows the therapeutic effect of ocular occlusion.

Abstract Background Lumbar interbody fusion is a recognized surgical technique in treatment of degenerative lumbar instability. Interbody fusion supplemented with pedicle screw fixation has several advantages over posterolateral fusion and has been advocated to improve fusion rates and clinical outcomes. Interbody fusion places the bone graft in the loadbearing position of the anterior and middle spinal columns thereby enhancing the potential for fusion. In addition, the interbody space has more vascularity than the posterolateral space, also increasing the potential for a solid fusion mass to form. Aim of the Work to assess safety and efficacy of unilateral pedicle screw fixation associated with interbody fusion in Lumbar spine degenerative diseases and to evaluate and compare outcomes of unilateral versus bilateral pedicle screw fixation associated with interbody fusion in lumbar spine degenerative diseases, as regard the operation time, bleeding, postoperative stay, cost, and the clinical and biomechanical results. Material & Methods This observational prospective comparative study of the 2 groups who were operated either unilateral (Group A /25 patients) or bilateral (Group B/25 patients) pedicle screw fixation with interbody fusion was done. Patients were followed up for 1, 6, 12 months. This study occurred at Ain Shams University hospitals. Results No differences were observed between the two groups with respect to demographic data. The patients of the two groups had significant improvement in functional outcome compared to preoperatively, except in early postoperative VAS back and ODI in unilateral group which is better than bilateral group. However, no significant difference noticed in the further follow up. There was no significant difference comparing fusion rate, complication rate and duration of hospital stay between the two groups at postoperative follow-up. There was significantly less blood loss, shorter postoperative pain killer use and significantly shorter operation time in the unilateral PS fixation group as compared with the bilateral PS fixation group in our study. Conclusion Our study suggested TLIF with unilateral PS fixation was as safe and effective as that with bilateral PS fixation. Unilateral PS fixation may significantly reduce the intraoperative blood loss and shorten the operation time, somewhat improve the clinical outcome scores of ODI and VAS Back without significant difference comparing fusion rate, complication rate and duration of hospital stay between the two groups at postoperative follow-up. BPSF with TLIF likely causes more degeneration at the cranial adjacent segment compared with UPSF techniques. However, the long-term follow up is required to demonstrate the impact of these findings.

Fertility of in vitro-produced embryos is affected by embryo stage and quality. Embryos quality 1 and stage 7 result in higher fertility than embryos of earlier stages and/or lower quality. The objective was to evaluate the effect of unilateral and bilateral transfer of 2 in vitro-produced embryos of earlier stages and/or poor quality on fertility. Heifers were synchronized using a 5-day CIDR Synch or 2 prostaglandin F2α injections 14 days apart followed by oestrus detection. Embryo transfer was performed 7 ± 1 day after gonadotropin-releasing hormone/oestrus and heifers were assigned randomly to 1 of 3 groups: single embryo ipsilateral to the corpus luteum (single; n = 188); 2 embryos in the uterine horn ipsilateral to the corpus luteum (unilateral; n = 138); 2 embryos bilaterally (bilateral; n = 128). Embryos stage 4 to 8 and quality 1 or 2 were randomly assigned to treatment groups. All embryos were 7-day fresh in vitro-produced embryos, and pregnancy diagnosis was performed by ultrasonography on Days 32 and 60. Data were analysed by logistic regression. Conception rates on Days 32 and 60 were not different (P > 0.10) between heifers receiving a single embryo [Day 32 = 30.9% (58/188) and Day 60 = 25% (47/188)] or those receiving 2 embryos [Day 32 = 36.5% (97/266) and Day 60 = 22.2% (59/266)]. However, pregnancy loss between Days 32 and 60 was greater (P < 0.01) in heifers with 2 embryos (39.2%; 38/97) than in those with a single embryo (18.9%; 11/58). Conception rate on Day 32 was not different between groups (P = 0.4) and was 30.9% (58/188) for single, 36.9% (51/138) for unilateral, and 35.9% (46/128) for bilateral. Similarly, there was no difference (P = 0.8) in conception rates on Day 60, single = 25% (47/188), unilateral = 23.9% (33/138), and bilateral= 20.3% (26/128). However, there was an effect of group on pregnancy loss between Days 32 and 60 (P = 0.04). Losses were higher (P = 0.01) in the bilateral group [43.5% (20/46)] compared with the single group [18.9% (11/58)], and the unilateral group was intermediate [35.3% (18/51)] and tended to be different from the single group (P = 0.1). Interestingly, when pregnancy loss was compared between heifers with twin or single pregnancies, as determined by ultrasonography, and regardless of the number of embryos transferred or their location, twin pregnancies had a greater pregnancy loss [62.1% (18/29)] compared with single pregnancies [24.6% (31/126); P < 0.01]. For twin bearing heifers, as determined by ultrasonography on Day 32, pregnancy loss did not differ between unilateral (62.5%; 10/16) and bilateral (61.5%; 8/13) transfers (P = 0.9). Similarly, there was no difference (P = 0.2) for heifers with single embryo pregnancies: single (18.9%; 11/58), unilateral (22.9%; 8/35), bilateral (36.4%; 12/33), although bilateral transfer of 2 embryos tended to be higher than single (P = 0.07). Transfer of 2 low quality in vitro-produced embryos results in similar conception rates, although pregnancy losses are greater. Interestingly, only 30% (29/97) of the pregnancies from heifers that received 2 embryos contained twins, indicating the loss of one of the embryos before Day 32. Furthermore, the increased losses observed with the transfer of 2 embryos were attributed to those heifers in which twin pregnancies were diagnosed on Day 32 regardless of distribution.
