Assessment of Conduit-Assisted Primary Nerve Repair Strength With Varying Suture Size, Number, and Location.

Background: Outcomes following digital nerve repair are suboptimal despite much research and various methods of repair. Increased tensile strength of the repair and decreased suture material at the repair site may be 2 methods of improving biologic and biomechanical outcomes, and conduit-assisted repair can aid in achieving both of these goals. Methods: Ninety-nine fresh-frozen digital nerves were equally divided into 11 different groups. Each group uses a different combination of number of sutures at the coaptation site and number of sutures at each end of the nerve-conduit junction, as well as 2 calibers of nylon suture. Nerves were transected, repaired with these various suture configurations using an AxoGuard conduit, and loaded to failure. Results: The 2-way analysis of variance (ANOVA) showed that repairs performed with 8-0 suture have significantly higher maximum failure load compared with 9-0 suture repairs (P < .01). Increasing the number of sutures in the repair significantly increased the maximum failure load in all groups regardless of suture caliber used (P < .01). Repairs with 9-0 suture at the coaptation site did not jeopardize repair strength when compared with 8-0 suture. Conclusions: Conduit-assisted primary digital nerve repairs with 8-0 suture increases the maximum load to failure compared with repairs with 9-0 suture, as does increasing the overall number of sutures. Using 9-0 suture at the coaptation site with 8-0 suture at the nerve-conduit junction does not jeopardize tensile strength when compared with similar repairs using all 8-0 suture and may decrease inflammation at the repair site while still achieving sufficient tensile strength.

Outcome of Achilles tendon plication and transfer of peroneus longus to Achilles tendon for correction of dynamic calcaneo-valgus deformity of the foot in post-polio residual paralysis

Objective: Tendon transfers are indicated when dynamic muscle imbalance results in a deformity that interferes with ambulation or function of the extremities. Foot and ankle are the most dependent parts of the body and are subjected to greater strain than other parts. Calcaneo-valgus deformity is one of the common deformities seen in Post-Polio Residual Paralysis. A host of operative procedures have been described in the management of this deformity. We report the results of the study conducted in our institute where Achilles tendon plication and transfer of Peroneus Longus tendon to Achilles tendon has been done for dynamic calcaneo-valgus deformity of the foot in patients of post-polio residual paralysis. Methods: This is a prospective study of 37 patients with Calcaneovalgus deformity having Post-Polio Residual Paralysis presenting to Balaji Institute of Surgery, Research and Rehabilitation for the Disabled Hospital from December 2009 to December 2012. Informed consent was taken from the parents of all the patients. Ethical committee approval was also taken. Patients with age more than 7 years, ability to walk without support and Peroneal tendon having minimum motor power of grade 4 or 5 as per MRC classification are included in our study. Patients with fixed deformity at ankle joint or subtalar joint are excluded from the study. Pre-operative evaluation included detailed motor examination of the involved lower limbs as per MRC (Medical research council) classification, evaluation of deformity in the hip and knee and range of motion at ankle. AOFAS (American Orthopaedic Foot and Ankle Society) clinical rating system was used to assess the patient pre-operatively and post-operatively. The aggregate score of the AOFAS ankle-hind foot clinical rating scale pre and post operatively were analyzed with use of chi-square analysis. The level of significance of < 0.05 was considered to be significant. The surgical procedure was done under spinal anesthesia with the patient in lateral position under pneumatic tourniquet. A longitudinal incision is made starting from the tip of lateral malleolus midway between the posterior border of lateral malleolus & Achilles tendon to about 8-10cm proximally. Skin flaps are mobilized without dissecting the subcutaneous fat. The two peroneal tendons are identified as they pass down the leg and around the back of the lateral malleolus. The peroneus longus tendon is divided as distally as possible and mobilized. Similarly the Achilles tendon is identified. Plication of the Achilles tendon is done in its middle third with nylon sutures and the peroneus longus tendon is transferred through it using Fish-Mouth (Pulvertaft) tendon suturing technique and is secured over itself proximally under tension providing the tenodesis effect. While this is done the ankle is kept in plantar flexion. The deep fascia is closed over the tendon. Pneumatic tourniquet was released, and the incision was closed in layers after hemostasis was achieved. Below knee cast is applied with the foot in plantar flexion. Movements of the toes are encouraged after recovery from anesthesia. Active toe movements were encouraged in the cast. After six weeks sutures are removed and ankle foot orthoses are provided for another six weeks. During this period supervised active exercises for strengthening the Tendoachilles (static cycling exercise) are started. Patient is reassessed after six weeks and the orthoses is discarded at this stage. Conclusion: Our experience concludes that Achilles tendon plication and transfer of peroneus longus tendon to Achilles tendon is an excellent procedure which improves the dynamic calcaneo-valgus deformity of foot in patients with post-polio residual paralysis. The advantage of the procedure being easy to do with very low complication rate and improves the quality of life in patients with post-polio residual paralysis. 37 patients with the dynamic calcaneo-valgus deformity of foot in patients with post-polio residual paralysis were analyzed with average follow up period of 12.5 months. Dynamic calcaneo-valgus deformity of the foot was corrected in 89.18% of patients. The study fared with 89 percent patients satisfied with the results. The patients showed improvement in their activity limitation, maximum walking distance, gait and stability.

Botulinum toxin A increases allograft tolerance in an experimental transplantation model: a preliminary study.

Identifying novel and safe immunosuppressants is of crucial importance. Recently, there have been several studies revealing that botulinum toxin A (BoTA) significantly alleviates ischemia–reperfusion injuries. Emerging evidence shows that ischemia–reperfusion injuries contribute to innate immune activation, promoting rejection, and inhibiting tolerance. Therefore, we hypothesized that a pretreatment with BoTA might decrease allograft rejection in a rat transplantation model. Twenty-four Lewis (LEW) rats were randomly assigned into two groups consisting of 12 rats each, depending on whether skin allograft was performed after pretreatment with BoTA (BoTA group) or with normal saline (control group). The experimental group was pretreated with a subcutaneous injection of BoTA (10 IU), while the control group was pretreated with normal saline 5 days prior to surgery. The donor Brown–Norway (BN) rat dorsal skin was subsequently grafted to the recipient LEW rats. The recipient wounds, measuring 2 cm × 2 cm, were made via dorsal skin excision through the panniculus carnosus. The donor skins of the same dimensions were obtained and transplanted on to the wounds and sutured with 4-0 nylon sutures. Mean graft survival time was measured in both groups. Quantitative reverse-transcriptase PCR and Western blotting were performed to evaluate the gene/protein expression of CD4 and VEGF. The mean graft survival time in the BoTA group was significantly longer than that of the control group (P=0.004). The relative mRNA and protein expression of CD4 was significantly lower in the BoTA group (P<0.001), while the relative mRNA and protein expression of VEGF was significantly higher in the BoTA group (P<0.001). In conclusion, our results show that BoTA prolongs the survival of skin allografts in a rat transplantation model.

Double Rhomboid Suture Technique for Congenital Ptosis.

Congenital ptosis is a troubling eye condition for pediatric ophthalmologists. There are many considerations to contemplate when deciding when to operate and which technique to use. A retrospective chart review of 69 pediatric patients treated for congenital ptosis using a double rhomboid frontalis sling with a nylon suture at a single tertiary care center. For patients with more than 6 months of follow-up, there were 38 patients with 46 primary surgeries (22 [58%] males and 16 [42%] females). The average age at the first surgery was 39.34 ± 33.18 months. There was a mean follow-up time of 51.87 ± 53.79 months. There were 7 children who needed one revision and 1 child who needed a second revision, equaling a 23.9% rate of revision. Patients who had surgery before the age of 3 years had a statistically significant likelihood of needing a second surgery (chi-square test = 7.246, P = .007, 95% confidence interval = 0.027 to 0.687). It was also statistically significant (P < .05) that, throughout childhood, older patients were less likely to need a revision. A double rhomboid frontalis sling using a nylon suture is an effective technique to treat congenital ptosis. This technique is easy to master and has a low cost compared to techniques involving autografts and allografts. It is also important to advise the family of the likelihood of a second surgery if there is a need to operate at a young age. [J Pediatr Ophthalmol Strabismus. 2018;55(2):117-121.].

Remote Limb Ischemic Conditioning during Cerebral Ischemia Reduces Infarct Size through Enhanced Collateral Circulation in Murine Focal Cerebral Ischemia

Remote ischemic conditioning (RIC) induces protection in focal cerebral ischemia. The conditioning is divided into pre-, per-, and postconditioning. However, the mechanisms of RIC remain unknown. This study aimed to determine the most effective subtype of RIC. We also examined involvement of collateral circulation on RIC. Transient middle cerebral artery occlusion (MCAO) was performed with nylon sutures in adult C57BL/6 mice under the monitoring of cerebral blood flow (CBF). Fifty mice were divided into 5 groups: MCAO control group, delayed pre-RIC group (RIC 24 hours before MCAO), early pre-RIC group (RIC 5 minutes before MCAO), per-RIC group (RIC during MCAO), and post-RIC group (RIC 5 minutes after MCAO). In other middle cerebral artery (MCA) control and per-RIC groups, collateral circulation was visualized with latex compound perfusion. After MCAO, CBF was reduced by 80% in all groups. At the end of MCAO, relative increase in CBF in per-RIC group was significantly greater than that in MCA control, whereas the infarct volume in per-RIC group was significantly smaller than that in other groups. The diameter of leptomeningeal anastomosis was larger in the per-RIC group than that in the control group. Among the 4 RIC procedures, only the per-RIC group showed clear brain protection. Enhancement of collateral circulation could play a role in the protective effect of per-RIC.

Comparative analysis of non-absorbable 10-0 nylon sutures with absorbable 10-0 Vicryl sutures in pediatric cataract surgery

Purpose:The purpose of the study is to compare the efficiency as well as the rate and type of suture-related complications between 10-0 monofilament nylon (Aurolab Nylon Sutures, double arm, Aurolab) and 10-0 polyglactin 910 sutures (Vicryl, single arm, Aurolab) for pediatric cataract surgery.Methods:It is a prospective, comparative study performed in children who underwent surgery for congenital or developmental cataract from March 2013 to February 2016. Patients underwent suturing with either nylon or Vicryl in unilateral cases, but in most bilateral surgeries, one eye received Vicryl sutures while the other eye received nylon. The sutures were compared for their complications and the need for suture removal.Results:Forty-one children (72 eyes) were included in the study, of which 31 children (62 eyes) underwent bilateral surgery while 10 (10 eyes) underwent unilateral surgery. Sixty-four nylon sutures were placed in 32 children (34 eyes), of which 22 (34.4%) were removed due to suture-related complications, whereas 14 (19.7%) (P = 0.03) of the 71 Vicryl sutures placed in 32 children (38 eyes) needed suture removal at an average of 2.9 weeks with the earliest at 6 days postoperatively. The odds of Vicryl suture being removed was 0.42 times with respect to nylon. The most common reason encountered for suture removal in both the materials was sutures becoming loose (16.3%), followed by vascularization (14.1%), infiltration (1.5%), and opacification (4.4%).Conclusion:Absorbable suture such as 10-0 Vicryl is preferred over nonabsorbable suture 10-0 nylon for suturing incisions in pediatric cataract surgery, to avoid subjecting the child to repeated anesthesia.

Lymphatic Venous Anastomosis Can Release the Lymphedema-Associated Pain of Upper Limb after Breast Cancer Treatment

Background Sometimes, chronic pain in the arm or chest could occur in postmastectomy patients. Although the pathology of the pain is unclear, the involvement of neurological mechanism, cicatricial contracture, or lymphedema is considered. The purpose of this study was to investigate the effectiveness of lymphaticovenous anastomosis (LVA) in reducing chronic pain in upper limb lymphedema patients. Patients and Methods This prospective study included consecutive 13 patients with upper limb lymphedema who received LVA. Preoperative lymphoscintigraphy and indocyanine green lymphography were performed. Pre- and postoperative pain scale were recorded using the visual analog scale (VAS). The number of cellulitis 1 year before and after LVA were compared. LVA was performed under local anesthesia, using a surgical microscope, and 12–0 nylon suture was used in the anastomosis. Results Two out of 13 patients were excluded from this study, and 11 patients were subjected to this study. All subjects were females with an average age of 64.3 years. The average lymphedema duration was 76.7 months. The average number of LVA sites was 5.7 per limb and the average follow-up period was 10.6 months. The average pre- and postoperative VAS scores were 3.5 and 0.59, respectively; the significant decrease was observed (p = 0.017). Three of the patients who had experienced cellulitis (once, twice, and four times, respectively) did not develop any cellulitis after LVA. Conclusion LVA was shown to be an effective surgical remedy for treating the lymphedema-associated pain of upper limb after breast cancer treatment.

A comparative study of immediate wound healing complications following cleft lip repair using either absorbable or non-absorbable skin sutures.

ObjectivesThe aim of the study was to compare wound healing complications following the use of either absorbable or non-absorbable sutures for skin closure in cleft lip repair.Materials and MethodsThis was a randomized controlled trial conducted at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Idi Araba, Lagos State, Nigeria. Sixty subjects who required either primary or secondary cleft lip repair and satisfied all the inclusion criteria were recruited and randomized into two groups (Vicryl group or Nylon group). The surgical wounds in all subjects were examined on 3rd, 7th, and 14th postoperative days (POD) for presence or absence of tissue reactivity, wound dehiscence, and local wound infection.ResultsHemorrhage, tissue reactivity, wound dehiscence, and local wound infection were identified as wound healing complications following cleft lip repair. The incidence of postoperative wound healing complications on POD3 was 33.3%. Tissue reactivity was more common throughout the evaluation period with the use of an absorbable (Vicryl) suture compared to a non-absorbable (Nylon) suture, although the difference was statistically significant only on POD7 (P=0.002). There were no significant differences in the incidences of wound dehiscence and infection between the two groups throughout the observation period.ConclusionThere were no statistically significant differences in the incidences of wound dehiscence and surgical site wound infection following the use of either Vicryl or Nylon for skin closure during cleft lip repair. However, more cases of tissue reactivity were recorded in the Vicryl group than in the Nylon group on POD7. Particular attention must be paid to detect the occurrence of wound healing complications, most especially tissue reactivity, whenever a Vicryl suture is used for skin closure in cleft lip repair.

Allogeneic sclera graft combined autologous conjunctival flap for repairing the emergent corneal perforation

To report a palliative and alternative surgical procedure, allogeneic sclera graft combined with autologous conjunctival flap (ASGACF), employing to repair the large emergent corneal perforation. The detail protocol of the surgical procedure was characterized and four representative cases were reviewed. An allogeneic sclera graft and recipient bed were prepared as the traditional penetrating keratoplasty (PK). And then sutured the sclera graft to the bed with 10-0 nylon suture and covered with a pedicled autologous conjunctival flap in half size. In the follow-up, the ASGACF repaired all of the corneal perforations and restored the integral walls of eyeballs, in spite of one who underwent a second surgery. This surgical procedure provided a palliative method to repair the large emergent corneal perforation while there is the lack of a corneal graft.

Outcomes of pterygium surgery-glue versus autologous blood versus sutures for graft fixation-an analysis.

AIM:The aim of this study is to compare the surgical outcomes of pterygium excision with conjunctival autograft using sutures, fibrin glue (tisseel), and autologous blood for the management of primary pterygium.PATIENTS AND METHODS:A retrospective study done in 681 eyes with primary nasal pterygium. Excision of the pterygium was performed followed by closure of the bare sclera with conjunctival autograft using interrupted 10-0 monofilament nylon sutures in 173 eyes (Group 1), fibrin glue (tisseel-baxter healthcare corporation, westlake village, ca-91362 USA) in 351 eyes (Group 2), and autologous blood in 157 eyes (Group 3). Patients were followed up for a period of 5–52 months. During follow-up, graft-related complications such as recurrence, graft loss, graft retraction, granuloma if any were noted and compared among the three groups.RESULTS:A total of 681 eyes who had primary nasal pterygium were included in this study. Pterygium excision with conjunctival autograft was performed using 10-0 monofilament nylon interrupted sutures in 173 eyes (25.4%), tisseel fibrin glue in 351 eyes (51.54%), and autologous blood in 157 (23.05%) eyes. The mean duration of follow-up was 5–52 months. The overall recurrence rate was 2.9% (20 eyes). In Group 1, recurrence was seen in 5 eyes (2.89%), in Group 2, it was seen in 7 eyes (1.99%) and in Group 3, 8 eyes (5.10%). However, the recurrence rate was not significant (P = 0.160). The rate of graft retraction in the 3 study groups were 12 eyes (6.94%), 10 eyes (2.85%), and 56 eyes (35.67%) with a significant P < 0.001. Granuloma was seen in 2 eyes (1.16%), in Group 1, and in 1 eye (0.64%) in Group 3. Graft loss was seen in 3 eyes (1.73%), 4 eyes (1.14%), 6 eyes (3.82%) in Group 1, 2, and 3, respectively.CONCLUSION:The outcomes of the three most commonly performed surgical technique of conjunctival autograft fixation has shown us that all three techniques are equally comparable and can be offered to our patients with equally good results.

Quantification of Collagen Organization after Nerve Repair.

Background:Clinical outcomes after nerve injury and repair remain suboptimal. Patients may be plagued by poor functional recovery and painful neuroma at the repair site, characterized by disorganized collagen and sprouting axons. Collagen deposition during wound healing can be intrinsically imaged using second harmonic generation (SHG) microscopy. The purpose of this study was to develop a protocol for SHG imaging of nerves and to assess whether collagen alignment can be quantified after nerve repair.Methods:Sciatic nerve transection and epineural repair was performed in male rats. The contralateral nerves were used as intra-animal controls. Ten-millimeter nerve segments were harvested and fixed onto slides. SHG images were collected using a 20× objective on a multiphoton microscope. Collagen fiber alignment was calculated using CurveAlign software. Alignment was calculated on a scale from 0 to 1, where 1 represents perfect alignment. Statistical analysis was performed using a linear mixed-effects model.Results:Eight male rats underwent right sciatic nerve repair using 9-0 Nylon suture. There were gross variations in collagen fiber organization in the repaired nerves compared with the controls. Quantitatively, collagen fibers were more aligned in the control nerves (mean alignment 0.754, SE 0.055) than in the repairs (mean alignment 0.413, SE 0.047; P < 0.001).Conclusions:SHG microscopy can be used to quantitate collagen after nerve repair via fiber alignment. Given that the development of neuroma likely reflects aberrant wound healing, ex vivo and/or in vivo SHG imaging may be useful for further investigation of the variables predisposing to neuroma.

The use of microfluidic spinning fiber as an ophthalmology suture showing the good anastomotic strength control

Adjusting the mechanical strength of a biomaterial to suit its intended application is very important for realizing beneficial outcomes. Microfluidic spinning fiber have been attracting attention recently due to their various advantages, but their mechanical strength has unfortunately not been a subject of concentrated research, and this lack of research has severely limited their applications. In the current work, we showed the mechanical properties of microfibers can be tuned easily and provided a mathematical explanation for how the microfluidic spinning method intrinsically controls the mechanical properties of a microfluidic spinning fiber. But we were also able to adjust the mechanical properties of such fibers in various other ways, including by using biomolecules to coat the fiber or mixing the biomolecules with the primary component of the fiber and by using a customized twisting machine to change the number of single microfiber strands forming the fiber. We used the bundle fiber as an ophthalmology suture that resulted in a porcine eye with a smoother post-operative surface than did a nylon suture. The results showed the possibility that the proposed method can solve current problems of the microfibers in practical applications, and can thus extend the range of applications of these microfibers.

Label-Free In Vivo Imaging of Corneal Lymphatic Vessels Using Microscopic Optical Coherence Tomography

Corneal neovascularization, in particular lymphangiogenesis, is a limiting factor in corneal transplant survival. Novel treatment approaches focus on (selective) inhibition and regression of lymphatic vessels. Imaging clinically invisible corneal lymphatic vessels is a prerequisite for these strategies. Using a murine model, this study investigates whether corneal lymphatic vessels can be imaged using microscopic optical coherence tomography (mOCT). Corneal neovascularization was induced by intrastromal placement of 11.0 nylon sutures in one eye of BALB/c mice. After 2 weeks, cross-sectional images and volumes of the corneas with a 0.5 mm lateral and axial field of view were acquired using a custom-built mOCT system enabling a resolution of 1 μm at a B-scan rate of 165/s. Three of the six animals received an additional intrastromal injection of India ink 24 hours before the measurement to stain the corneal lymphatic system in vivo. Immunohistochemistry using CD31 and LYVE-1 was used to validate the mOCT findings. Using mOCT, lymphatic vessels were visible as dark vessel-like structures with the lumen lacking a hyperreflective wall and mostly lacking cells. However, individual, slowly moving particles, which most likely are immune cells, occasionally could be observed inside the lumen. In lymphatic vessels of ink-stained corneas, hyperreflection and shadowing underneath was observed. Ink-filled lymphatic vessels were colocalized in consecutive corneal flat mounts of the same specimen. Corneal lymphatic vessels can be imaged using mOCT. This novel approach opens new options for noninvasive clinical imaging of corneal lymphatic vessels for diagnostic and therapeutic indications.

Effect of Suture Removal on Refraction and Graft Curvature After Deep Anterior Lamellar Keratoplasty in Patients With Keratoconus.

To evaluate the effect of suture removal on refraction and keratometry measurements after deep anterior lamellar keratoplasty (DALK). This retrospective study enrolled 54 keratoconus-affected eyes that underwent DALK. A combined suturing technique consisting of a 16-bite single running and 8-bite interrupted 10-0 nylon sutures was used at the time of keratoplasty. Selective interrupted suture removal was performed in a subgroup of patients to reduce postkeratoplasty astigmatism. In another subgroup, all sutures were removed at a single session. Adjustment of the running suture tension was not performed in any case. The effect of suture removal on refractive outcomes was investigated in the entire study group, and the 2 subgroups were compared. Mean patient age was 26.6 ± 6.7 years at the time of keratoplasty. The mean interval from surgery to complete suture removal was 17.4 ± 5.9 months. Compared with the pre-suture removal values, there was a significant increase in the magnitude of myopia (-1.12 ± 1.73 D, P = 0.001), refractive astigmatism (-0.89 ± 2.47 D, P = 0.04), mean keratometry (1.39 ± 1.64 D, P = 0.001), and keratometric astigmatism (2.61 ± 2.43 D, P < 0.001) after complete suture removal. Subgroup analysis revealed that selective removal of interrupted sutures was effective as long as remaining interrupted and running sutures were left in place. Complete suture removal was followed by an unpredictable and significant increase in post-DALK refraction and keratometry readings. In the subgroup that underwent early selective removal of interrupted sutures before complete suture removal, the desirable effects of this procedure significantly diminished after all remaining sutures were completely removed.

Characterization and mechanical testing of polydopamine-adhered electroless copper films

Self-assembling polydopamine has shown great versatility as a multifunctional surface coating. This study investigates the adhesive properties of polydopamine used to bind electroless copper films to several polymer substrates widely used for commercial applications, including polyethylene (PE), polycarbonate (PC), poly(methyl methacrylate) (PMMA), and nylon 6,6. Each substrate was coated in a similar manner resulting in continuous copper films of 52±12nm in thickness. Transmission electron microscopy revealed a non-preferential polycrystalline microstructure of copper grains averaging 53±17nm in diameter with a range of 21nm to 123nm, indicating there is some overlap of grains in the film. Peel testing, tensile tests, and tribological oscillating wear tests were used to characterize the mechanical performance of the adhered copper films. The nylon substrate had the highest peel strength, 49±5mN/mm, while the remaining substrates ranged from 5 to 13mN/mm on average. Coated substrates were strained up to 20% tensile strain to investigate film delamination, buckling, and rupture. Transverse buckling of the films relative to the direction of strain was observed due to Poisson's effect during tension. Films on nylon substrates resisted buckling and rupture up to 20% strain, whereas buckling, delamination, and rupture was observed in the other substrates below 20% strain. Tribological testing revealed that the coefficient of friction was governed by the polymer substrate and was not dependent upon the polydopamine or copper films. As a demonstration of the robust nature of this method, a nylon suture was coated with polydopamine-adhered copper film and tied in a knot to show a large complex deformation state without showing signs of delamination.
