Prognostic factors for the success of BPH/BPO surgery in patients with suprapubic tube

Introduction. In patients with suprapubic tube (SPT) surgical restoration of voiding is not 100% successful. Sometimes urination is inadequate or not recovered at all.Objective. To determine factors influencing the outcomes of benign prostatic hyperplasia / benign prostate obstruction (BPH/BPO) surgery in patients with cystostomy drainage.Materials & methods. The study included 52 men with suprapubic tube initially placed for urinary retention caused by prostate hyperplasia. Afterwards, all patients underwent transurethral resection of the prostate. The age of the patients ranged from 48 to 85 years old. Clinical and urodynamic data of the patients were analysed, restoration of adequate urination after surgery was evaluated as well. We took into account patients age, IPSS scores, bacterial growth in the urine culture test, number of episodes of urinary retention, volume of urinary retention prior to cystostomy, prostate volume, intravesical prostate growth, detrusor overactivity and ability to void in the presence of SPT.Results. We were unable to achieve adequate bladder emptying after transurethral resection of the prostate in 4 (7.6%) patients. These patients required continued bladder drainage after surgery. In 48 (92.4%), adequate urination was restored after surgery and cystostomy drains were removed. Patients with one or more of the following characteristics were more likely to experience a failure of surgical treatment: age over 80, residual urine volume over 1500 mL, and absence of overactive bladder.Conclusion. The study indicates that use of cystometry prior to BPH/BPO surgery is reasonable in such patients. Feasibility of BPH/BPO surgery for this group of patients should be considered individually.

Atypical Presentation of Idiopathic Intracranial Hypertension: A Case Series and Literature Review.

Idiopathic intracranial hypertension (IIH) is a condition in which intracranial pressure (ICP) increases without an apparent cause. Typically, patients present with headaches, dizziness, pulsatile tinnitus, visual disturbances, blurred vision, diplopia, photophobia, visual field defects, and papilledema on fundoscopy. The association between IIH, spontaneous cerebrospinal fluid (CSF) rhinorrhea, and arachnoid cysts has been discussed in the literature; however, there is no clear explanation for this association. We aimed to present a series of four patients with a confirmed diagnosis of IIH with atypical presentations, discuss the management of each case, and provide an explanation for this association to alert clinicians to the atypical presentation of IIH and facilitate early diagnosis and proper treatment of this condition by CSF diversion. This was a retrospective case series of all patients who were diagnosed with IIH and showed improvement after ventriculoperitoneal shunt insertion after failure of at least one operative intervention resulting from primary radiological and clinical findings in 2001 to 2022. Data on demographics, clinical presentation, radiological findings, surgical management, and diagnostic criteria for IIH were recorded. We identified four patients with a confirmed diagnosis of IIH who presented with atypical presentations as follows: intracranial arachnoid cyst, cervical spine arachnoid cyst, giant Virchow perivascular space, and spontaneous CSF (CSF) rhinorrhea. All patients responded to CSF diversion after failure of surgical treatment targeting the primary pathology. IIH should be suspected after the failure of primary surgical treatment in cases of spontaneous CSF rhinorrhea, spinal and cranial arachnoid cysts, and symptomatic ventriculoperitoneal shunt. Treatment in such situations should be directed toward IIH with CSF diversion.

Three-year outcomes of a randomized clinical trial of perioperative vaginal estrogen as adjunct to native tissue vaginal apical prolapse repair

As the muscular and connective tissue components of the vagina are estrogen responsive, clinicians may recommend vaginal estrogen to optimize tissues preoperatively and as a possible means to reduce prolapse recurrence, but long-term effects of perioperative intravaginal estrogen on surgical prolapse management are uncertain. This study aimed to compare the efficacy of perioperative vaginal estrogen vs placebo cream in reducing composite surgical treatment failure 36 months after native tissue transvaginal prolapse repair. This was an extended follow-up of a randomized superiority trial conducted at 3 tertiary US sites. Postmenopausal patients with bothersome anterior or apical vaginal prolapse were randomized 1:1 to 1-g conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally twice weekly for ≥5 weeks preoperatively and continued twice weekly for 12 months postoperatively. All participants underwent vaginal hysterectomy (if the uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The primary report's outcome was time to failure by 12 months postoperatively, defined by a composite outcome of objective prolapse of the anterior or posterior walls beyond the hymen or the vaginal apex descending below one-third the total vaginal length, subjective bulge symptoms, and/or retreatment. After 12 months, participants could choose to use-or not use-vaginal estrogen for atrophy symptom bother. The secondary outcomes included Pelvic Organ Prolapse Quantification points, subjective prolapse symptom severity using the Patient Global Impression of Severity and the Patient Global Impression of Improvement, and prolapse-specific subscales of the 20-Item Pelvic Floor Distress Inventory and the Pelvic Floor Impact Questionnaire-Short Form 7. Data were analyzed as intent to treat and "per protocol" (ie, ≥50% of expected cream use per medication diary). Of 206 postmenopausal patients, 199 were randomized, and 186 underwent surgery. Moreover, 164 postmenopausal patients (88.2%) provided 36-month data. The mean age was 65.0 years (standard deviation, 6.7). The characteristics were similar at baseline between the groups. Composite surgical failure rates were not significantly different between the estrogen group and the placebo group through 36 months, with model-estimated failure rates of 32.6% (95% confidence interval, 21.6%-42.0%) and 26.8% (95% confidence interval, 15.8%-36.3%), respectively (adjusted hazard ratio, 1.55; 95% confidence interval, 0.90-2.66; P=.11). The results were similar for the per-protocol analysis. Objective failures were more common than subjective failures, combined objective and subjective failures, or retreatment. Using the Patient Global Impression of Improvement, 75 of 80 estrogen participants (94%) and 72 of 76 placebo participants (95%) providing 36-month data reported that they were much or very much better 36 months after surgery (P>.99). These data included reports from 51 of 55 "surgical failures." Pelvic Organ Prolapse Quantification measurements, Patient Global Impression of Severity scores, and prolapse subscale scores of the 20-Item Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire-Short Form 7 all significantly improved for both the estrogen and placebo groups from baseline to 36 months postoperatively without differences between the groups. Of the 160 participants providing data on vaginal estrogen usage at 36 months postoperatively, 40 of 82 participants (49%) originally assigned to the estrogen group were using prescribed vaginal estrogen, and 47 of 78 participants (60%) assigned to the placebo group were using vaginal estrogen (P=.15). Adjunctive perioperative vaginal estrogen applied ≥5 weeks preoperatively and 12 months postoperatively did not improve surgical success rates 36 months after uterosacral or sacrospinous ligament suspension prolapse repair. Patient perception of improvement remained very high at 36 months.

Repair of a fistula between the aorta and right ventricular outflow tract secondary to infective endocarditis of a unicuspid aortic valve and previously repaired ventricular septal defect

BackgroundInfective endocarditis of the aortic valve can result in a wide range of destructive pathology beyond the valve leaflets and annulus which require careful surgical planning to provide appropriate debridement and reconstruction. Failure to do so can result in a failure of surgical treatment, recurrent infection and cardiac failure with concomitant high morbidity and mortality.Case reportWe describe the case of a 45-year-old male with previous patch repair of a ventricular septal defect, who was diagnosed with sub-acute bacterial endocarditis of the native aortic valve and developed a new fistula from the aorta to the right ventricular outflow tract which. This was managed surgically.ConclusionThis unique case highlights another spectrum of infective endocarditis with a unique approach to repair and management.

Superficial branch of the radial nerve regularly contains fibers from the lateral antebrachial cutaneous nerve: A role in neuroma treatment

BackgroundMany surgical strategies aim to treat the symptomatic neuroma of the superficial branch of the radial nerve (SBRN). It is still difficult to treat despite many attempts to reveal a reason for surgical treatment failure. The lateral antebrachial cutaneous nerve (LACN) is known to overlap and communicate with SBRN. Our study aims to determine the frequency of spreading of LACN fibers into SBRN branches through a microscopic dissection to predict where and how often LACN fibers may be involved in SBRN neuroma. MethodsEighty-seven cadaveric forearms were thoroughly dissected. The path of LACN fibers through the SBRN branching was ascertained using microscopic dissection. Distances between the interstyloid line and entry of LACN fibers into the SBRN and emerging and bifurcation points of the SBRN were measured. ResultsThe LACN fibers joined the SBRN at a mean distance of 1.7 ± 2.5 cm proximal to the interstyloid line. The SBRN contained fibers from the LACN in 62% of cases. Most commonly, there were LACN fibers within the SBRN’s third branch (59%), but they were also observed within the first branch, the second branch, and their common trunk (21%, 9.2%, and 22%, respectively). The lowest rate of the LACN fibers was found within the SBRN trunk (6.9%). ConclusionThe SBRN contains LACN fibers in almost 2/3 of the cases, therefore, the denervation of both nerves might be required to treat the neuroma. However, the method must be considered based on the particular clinical situation.

Reasons for failure of surgical treatment of patients with congenital basal encephaloceles

Encephalocele or craniocerebral hernia is a disease in which there is a prolapse of the meninges and structures of the brain through a skull defect. Clinically, they are manifested by a violation of nasal breathing, deformation of the naso‑ethmoid region, and nasal liquorrhea. Various inflammatory complications (meningitis, meningoencephalitis, ventriculitis, brain abscess) can occur against the background of persistent hernia, while mortality is 8–10 %.Basal encephalocele is a rare pathology that requires an integrated approach in a specialized hospital using high‑tech equipment. Therapeutic tactics and risks are determined individually based on the patient’s age, current symptoms, size of the nasal cavity, location and size of the skull base defect. In the absence of nasal liquorrhea, it is possible to delay surgical treatment in order to be able to use an autologous bone of the calvarium, to collect a larger periosteal flap, to perform the operation using a combined approach and to minimize surgical complications. With endonasal endoscopic access, it is necessary to separate the encephalocele from the surrounding tissues, completely remove the hernial sac and visualize the bone edges of the defect, and then perform its plastic closure.Despite the fact that in most cases the existing methods of treatment are very effective, in a number of cases it is not possible to achieve the desired result. This article presents two rare clinical cases in which patients with basal encephalocele required reoperation for herniation and skull base defect repair.

What Is the Most Effective Treatment for Periprosthetic Joint Infection After Total Joint Arthroplasty in Patients with Rheumatoid Arthritis?: A Systematic Review.

Rheumatoid arthritis (RA) is a risk factor for periprosthetic joint infection (PJI) after total joint arthroplasty (TJA). The purpose of this study was to perform a systematic review comparing the failure rates of debridement, antibiotics, and implant retention (DAIR), one-stage exchange arthroplasty/revision (OSR), and 2-stage exchange arthroplasty/revision (TSR) for RA patients with PJI and identify risk factors in the RA population associated with increased treatment failure rate. PubMed, Ovid MEDLINE, and Ovid Embase databases were screened with the terms "rheumatoid arthritis," "total joint arthroplasty," "prosthetic joint infection," and "treatment for PJI" on August 29, 2021. Four hundred ninety-one studies were screened, of which 86 were evaluated. The primary outcome evaluated was failure of surgical treatment for PJI. Ten retrospective cohort studies were included after full-text screening, yielding 401 patients with RA. Additional demographic and PJI management data were obtained for 149 patients. Patients with RA who underwent TSR demonstrated a lower failure rate (26.8%) than both DAIR (60.1%) and OSR (39.2%) (χ2 = 37.463, p < 0.00001). Patients with RA who underwent DAIR had a 2.27 (95% CI, 1.66-3.10) times higher risk of experiencing treatment failure than those who underwent TSR. Among risk factors, there was a significant difference in the C-reactive protein of patients who did vs. did not experience treatment failure (p = 0.02). TSR has a higher rate of success in the management of PJI patients with RA compared with DAIR and OSR. The complete removal of the infected prosthesis and delayed reimplantation may lower the treatment failure rate. Level III.

Consensus on the definition and criteria for failure of surgical treatment in bacterial arthritis of a native joint: An international Delphi study.

The literature presents a wide range of success rates for a single surgical intervention of bacterial-septic-arthritis, and there is a lack of clear criteria for identifying treatment failure and making decisions about reintervention. This Delphi study aims to establish a consensus among an international panel of experts regarding the definition of treatment failure and the criteria for reintervention in case of bacterial arthritis. The conducting and reporting Delphi studies (CREDES) criteria were used. Data from a systematic review was provided as the basis for the study. A list of 100 potential experts were identified. The study was designed and conducted as follows: (I) identification and invitation of an expert panel, (II) informing the participating expert panel on the research question and subject, and (III) conducting two or three Delphi rounds to reach consensus on explicit research items. Potential criteria were rated on a five-point Likert scale. Sixty orthopaedic experts from nine countries participated in this Delphi study, with 55 completing all three rounds. The mean experience as an orthopaedic surgeon was 15 years (SD ± 9). Strong (96%) consensus was reached on the definition of treatment failure: the persistence of physical signs of arthritis (e.g., pain and swelling) and/or systemic inflammation (e.g., fever and no improvement in CRP) despite surgical and antibiotic treatment. Furthermore, consensus (>80%) was reached on six criteria influencing the decision for reintervention; pain (81%), sepsis (98%), fever (88%), serum CRP (93%), blood culture (82%), and synovial fluid culture (84%). The definition of treatment failure for bacterial arthritis after a single surgical intervention was established through a three-round Delphi study. Additionally, consensus was reached on six criteria that are helpful for determining the need for reintervention. This definition and these criteria may help in the development of clinical guidelines, and will empower physicians to make more precise and consistent decisions regarding reintervention for patients, ultimately aiming to reduce over- and undertreatment and improve patient outcomes.

Seizure Pathways Changes at the Subject-Specific Level via Dynamic Step Effective Network Analysis.

The variability in the propagation pathway in epilepsy is a main factor contributing to surgical treatment failure. Ways to accurately capture the brain propagation network and quantitatively assess its evolution remain poorly described. This work aims to develop a dynamic step effective network (dSTE) to obtain the propagation path network of multiple seizures in the same patient and explore the degree of dissimilarity. Multichannel stereo-electroencephalography (sEEG) signals were acquired with ictal processes involving continuous changes in information propagation. We utilized high-order dynamic brain networks to obtain propagation networks through different levels of linking steps. We proposed a dissimilarity index based on singular value decomposition to quantitatively compare seizure pathways. Simulated data were generated through The Virtual Brain, and the reliability of this method was verified through ablation experiments. By applying the proposed method to two datasets consisting of 29 patients total, the evolution processes of each patient's seizure networks was obtained, and the within-patient dissimilarities were quantitatively compared. Finally, three types of brain network connectivity patterns were found. Type I patients have a good prognosis, while type III patients are prone to postoperative recurrence. This method captures the evolution of seizure propagation networks and assesses their dissimilarity more reliably than existing methods, demonstrating good robustness for studying the propagation path differences for multiple seizures in epilepsy patients. The three different patterns will be important considerations when planning epilepsy surgery under sEEG guidance.

Intrarectal injections of botulinum toxin versus placebo for the treatment of urge faecal incontinence in adults (FI-Toxin): a double-blind, multicentre, randomised, controlled phase 3 study

Non-randomised studies assessing intrarectal botulinum toxin type A (BoNTA) injections for faecal incontinence are promising. We aimed to evaluate the efficacy of BoNTA for the treatment of faecal incontinence in a randomised study. In this randomised, double-blind, placebo-controlled study, we included adult patients who had at least one urgency or faecal incontinence episode per week for at least 3 months and who had experienced a failure of conservative or surgical treatment from eight French specialist hospital units with the skills to manage patients with faecal incontinence. Patients were randomly assigned (1:1) by a central web form to receive intrarectal submucosal injections of either 200 units of BoNTA (Botox; Allergan, Irvine, CA, USA; BoNTA group) or an equivalent volume of saline (placebo group), stratified by Cleveland Clinic Severity scores (CCS score; ≥12 or <12). Patients, investigators, study site staff, and sponsor personnel were masked to treatment allocation up to the 6-month visit. The primary endpoint was the number of episodes of faecal incontinence and urgency per day assessed using 21-day patient bowel diaries 3 months after the treatment. The primary analysis was performed using a modified intention-to-treat (mITT) approach (ie, in all the randomised patients who had received a treatment) with adjustment for baseline faecal incontinence and urgency episodes. After the final data collection at 6 months after injections, patients were unmasked and offered the BoNTA treatment if they were in the placebo group (rescue therapy) without masking, with an additional 6 months of safety follow-up. This trial is registered with ClinicalTrials.gov, number NCT02414425. Between Nov 25, 2015, and Nov 25, 2020, we randomly assigned 200 patients to receive either BoNTA (n=100) or placebo (n=100) injections. Due to withdrawals before the injections, 96 patients were included in the BoNTA group and 95 patients were included in the placebo group (mITT analysis). The mean number of faecal incontinence and urgency episodes per day in the BoNTA group decreased from 1·9 (SD 2·2) at baseline to 0·8 (1·8) at 3 months after the injections, and from 1·4 (1·1) to 1·0 (1·0) in the placebo group, with a baseline-adjusted mean group difference at 3 months estimated at -0·51 (95% CI -0·80 to -0·21, p=0·0008). No serious treatment-related adverse events were reported in the trial. The most frequently reported non-serious adverse event (treatment related or not) following the BoNTA or placebo injections was constipation (reported in 68 [40%] of 169 patients who received the BoNTA injections and 38 [40%] of 95 patients who received placebo injections). BoNTA injections are an efficacious treatment for urge faecal incontinence. Further research will define the optimum selection criteria, dose, site of injection, re-injection frequency, and long-term results. General Direction of Healthcare (French Ministry of Health).

Biomimetic fusion liposomes boosting antitumor immunity and promote memory T cell differentiation to inhibit postoperative recurrence of breast cancer

For most solid tumors, surgery is still the most effective treatment. However, postoperative recurrence is the main reason for the failure of surgical treatment of malignant tumors. It is urgent to develop new nanomedicine systems to inhibit postoperative recurrence. Here, we designed a tumor cell membrane fusion liposome loaded AIE photosensitizer and Metformin named TMFL to inhibit postoperative recurrence. First, thanks to the homing effect of tumor cell membranes, TMFL can enter tumor tissues through active targeting. Under light irradiation, TMFL can produce singlet oxygen (1O2), which promoted immunogenic cell death (ICD) of tumor cells, thereby inducing dendritic cell (DC) maturation and stimulating T cell immunity. Metformin released by TMFL further promoted T cell differentiation into Central Memory T cell (Tcm) and inhibited tumor recurrence. The results of experiments showed that TMFL plus light treatment increased the content of mature DC in lymph nodes. In addition, TMFL can effectively promote the differentiation of T cells into Tcm, increase the content of T cells in recurrent tumor tissue, and inhibit the tumor recurrence. In view of the current major problems such as postoperative tumor recurrence, our TMFL system has a good clinical application potential.

Exploring the propagation pathway in individual patients with epilepsy: A stepwise effective connection approach

ObjectiveThe unclear propagation pathway of seizures is one of the main reasons for failure of surgical treatment, and the propagation process involves the directional brain networks. However, few network analysis techniques have successfully traced specific seizure propagation pathways. This study proposed a stepwise transfer entropy (STE) approach to describe the propagation of effective connections in brain networks. MethodsThe proposed STE technique is applied to stereoelectroencephalography (SEEG) data collected from patients with epilepsy, which can identify characteristic regions connected to specific seed brain regions at different link-step levels. Importantly, the underlying TE-based network construction method can accurately obtain electrode-to-electrode connections, and the stepwise approach can capture the interactions between electrodes at the connection level. Finally, simulation and clinical data were used to evaluate the STE approach according to the similarity, confusion matrix, accuracy and recall. ResultsWe used three datasets: a simulation dataset, a clinical dataset, and a public dataset. We compared the results of different network construction methods with multiple datasets, and the STE approach successfully captured node changes in epilepsy patients, effectively identified early and late propagation nodes, and determined the propagation pathway. Moreover, the STE approach is superior to other methods in all evaluation indices, achieving 97.9% accuracy and 0.93 similarity. SignificanceCompared with the existing methods, the STE approach has significant advantages in accurately tracking propagation pathways. Moreover, the STE approach is simple and quickly performs calculations, making it an easy-to-use promising method for determining propagation pathways in clinical settings.

Consecutive resections of double pituitary adenoma for resolution of Cushing disease: illustrative case.

Double pituitary adenomas are rare presentations of two distinct adenohypophyseal lesions seen in <1% of surgical cases. Increased rates of recurrence or persistence are reported in the resection of Cushing microadenomas and are attributed to the small tumor size and localization difficulties. The authors report a case of surgical treatment failure of Cushing disease because of the presence of a secondary pituitary adenoma. A 32-year-old woman with a history of prolactin excess and pituitary lesion presented with oligomenorrhea, weight gain, facial fullness, and hirsutism. Urinary and nighttime salivary cortisol elevation were elevated. Magnetic resonance imaging confirmed a 4-mm3 pituitary lesion. Inferior petrosal sinus sampling was diagnostic for Cushing disease. Primary endoscopic endonasal transsphenoidal resection was performed to remove what was determined to be a lactotroph-secreting tumor on immunohistochemistry with persistent hypercortisolism. Repeat resection yielded a corticotroph-secreting tumor and postoperative hypoadrenalism followed by long-term normalization of the hypothalamic-pituitary-adrenal axis. This case demonstrates the importance of multidisciplinary management and postoperative hormonal follow-up in patients with Cushing disease. Improved strategies for localization of the active tumor in double pituitary adenomas are essential for primary surgical success and resolution of endocrinopathies.

A Case Series of Distal Radius and Ulna Nonunion Treated with Minimal Surgical Intervention

Abstract Background We hypothesized a treatment guideline for ulna/radius nonunion after failed surgical treatment and propose to verify it in a prospective study. Herein, we report our preliminary findings and review the current trend. Methods Six patients who met the criteria were retrospectively investigated, and we further categorized “nonunion of both the radius/ulna” into four subcategories. For hypertrophic nonunion of the radius, but with stability maintained by a plate, we only reinforced the mechanical stability of the ulna (osteosynthesis, treatment option 1). In oligo- or atrophic nonunion of the radius with stability maintained by a plate, we added cancellous or tricortical bone grafts to the radius after osteosynthesis of the ulna (treatment option 2). In the presence of definitive pseudomotion of the radius (no stability), we performed revision osteosynthesis for the radius only, without (treatment option 3) or with bone graft (treatment option 4). Results Two, one, one, and two patients had corresponding treatment options of 1, 2, 3, and 4, respectively. At a mean postoperative time of 4.3 months, all radii and ulnas showed union. At the final follow-up, clinical outcomes in terms of the range of motion and VAS (visual analog scale)/DASH (disabilities of the arm, shoulder, and hand) scores were satisfactory. We are currently conducting a prospective trial to verify the hypothesized guidelines. For both types of radius/ulna nonunion, first, if the stability of the radius was good, we compared the final outcomes with or without revision osteosynthesis for the radius, in addition to osteosynthesis for the ulna. Second, if stability was absent in the radius, we compared the final outcomes with or without osteosynthesis of the ulna, in addition to revision osteosynthesis of the radius. Conclusions The treatment guidelines for rare nonunion after failed surgical treatment of both the distal radius/ulna were suggested according to the “concept of stability” based on the principles of fracture treatment. This hypothesis could be used to guide prospective studies of revision surgery for nonunion of both the radius and ulna. Level of Evidence Level IV, retrospective case series.

Augmentation of the Anterior Cruciate Ligament Using the Peroneus Longus: Description of the Surgical Technique

Background: The quadruple graft from the hamstring tendons has become a widely used option in the reconstruction of the anterior cruciate ligament (ACL), however, this graft may not have the desirable diameter for the reconstruction, increasing the risk of re-rupture. In this context, the peroneus longus tendon graft appears as an option to complement other grafts, transforming a thin quadruple graft into a sextuple graft. Indications: The sextuple graft technique for ACL reconstruction is used in patients who have a quadruple graft with a diameter of less than 8 mm, and due to its length, it is not possible to make a quintuple graft, for example. Technique Description: Initially, the hamstring tendons are removed with the aid of a tenotome. After that, the anterior half of the peroneus longus tendon is identified and removed. On the back table, the definitive graft is prepared so that we have a sextuple graft with a diameter greater than 8 mm. Finally, the ACL reconstruction is performed anatomically using an adjustable loop device in the femur and an interference screw in the tibia. Results: In our experience with patients who have a hamstring graft diameter of less than 8 mm, we obtained an average increase of 1.8 mm in graft diameter when augmentation was performed with the anterior half of the peroneus longus. Discussion: Grafts less than 8 mm in diameter are at increased risk of rupturing and failure of surgical treatment of the ACL injury. The surgeon must be prepared to make a quintuple or sextuple graft, but in some patients, the tendons are short or there is no availability of a tissue bank, making this practice impossible. The use of the anterior half of the peroneus longus to perform graft augmentation is safe, causing almost no morbidity to the donor area and is easily accessible during the procedure, making it an excellent option for increasing the diameter of thin grafts.

Non-vascularised corticocancellous (tricortical) iliac bone graft longer than 3 cm for non-union after failed surgical treatment

We hypothesised that traditional iliac tricortical bone grafts (no vascularised) still have a reasonable role in promoting satisfactory bony healing in non-union defects of certain sizes. Here, we report the clinical/radiological outcomes through a retrospective case series. We screened 74 patients with definitive non-union in the long bones of the upper extremities who visited the outpatient department from 2008 to 2018. Among these patients, 25 who met our inclusion/exclusion criteria were investigated. The mean age was 51.92 years, and there were 12, 9, 1, and 3 lesions of the radius, ulna, clavicle, and humerus, respectively. The tools for primary fixations were plate and intramedullary nails in 24 and 1 patients, respectively. Six patients presented with atrophic non-union. The mean period from a previous surgery was 6.84 months. The mean defective bone sizes were 1.81 and 3.50cm pre-debridement and post-debridement, respectively. All devices had locking plates longer than the previous plate, and the graft was concurrently fixed by screws in three patients. At a mean of 15.92 weeks after the revision surgery, all patients experienced union. At the final follow-up, the clinical outcomes were satisfactory. No significant differences in clinical outcomes were found according to the lesion, type of non-union, period from the previous surgery, or harvest length of the iliac bone. If the proper indications and some technical aspects are considered, a non-vascularised iliac bone graft longer than 3cm could still be a reasonable option for treating diaphyseal non-union of the upper extremities.

Expectant management of tubal pregnancies with human chorionic gonadotropin up to 2000 mIU/mL.

To describe outcomes of expectant management (EM) versus methotrexate (MTX) treatment in tubal pregnancies with pretreatment human chorionic gonadotropin (hCG) less than 2000 mIU/mL. This retrospective cohort from two tertiary hospitals included women with confirmed tubal pregnancies and pretreatment hCG <2000 mIU/mL. Exclusion criteria were unrecorded pregnancy site, unconfirmed diagnosis, and surgical treatment upon diagnosis. The primary outcome was eventual rate of surgical treatment. Between December 2009 and June 2021, 545 of 2114 (25.8%) women diagnosed with a tubal pregnancy met our inclusion criteria. We compared women who underwent EM (N = 201) with women who received MTX (N = 344). All women in the EM group had a declining trend of hCG. The MTX group had higher pretreatment hCG and higher rates of yolk sac or embryo presence on ultrasound. Eventual surgical treatment rate was higher in the MTX group compared with the EM group (39 [11.3%] vs. 9 [4.5%], P = 0.006), with no difference in the treatment failure rate or tubal rupture rate. In a subgroup analysis of women with pretreatment hCG between 1000 and 2000 mIU/mL, eventual surgical treatment, treatment failure, and tubal rupture rates did not differ between groups. Logistic regression analysis revealed that eventual surgical treatment was independently associated with hCG levels less than 1000 mIU/mL (adjusted odds ratio [aOR] 0.28, 95% confidence interval [CI] 0.14-0.56) and endometriosis (aOR 9.20, 95% CI 3.55-23.81). Expectant management of tubal pregnancies with pretreatment hCG levels less than 2000 mIU/mL and even between 1000 and 2000 mIU/mL and with a declining trend of hCG demonstrated lower or comparable rates of eventual surgical treatment, when compared with MTX treatment.

Unmasked Neuropathic Pain After Neurectomy: A Case Series and Review of the Literature

Summary: Localization of neuropathic pain to a specific peripheral nerve origin relies on patient history, physical examination, and nerve blocks. Neurectomy of the involved nerve(s) can successfully alleviate patients’ pain. However, a subset of patients postoperatively describe persistent pain, but say that the pain “moved” to a new location (eg, from the dorsum of the foot to the lateral foot). This may be viewed as a treatment failure by the patient and surgeon alike. Further investigation, however, may localize the new pain to an additional, separate peripheral nerve injury, which was previously unrecognized by both parties. The mechanism involved is that of pain masking and unmasking. Successful treatment of the more prominent pain stimulus allows for recognition of a second, less-offending peripheral nerve injury. As the field of surgical treatment of chronic peripheral neuropathic pain advances, it is important to identify and define specific nuances of diagnosis and treatment via neurectomy. The term “diffuse noxious inhibitory control,” used to describe the pain-inhibits-pain pathway, may help explain the phenomenon of masking, whereby one pain generator is more prominent and shields another site from recognition and subsequent diagnosis. In this context, unmasked pain should be considered as a potential source of surgical treatment failure. We present a series of patients who, following improvement in the initial location of their pain, reported pain in a distinctly new peripheral nerve distribution, leading to reoperation.

Prognostic factors associated with failure to return to sport following primary arthroscopic Bankart repair: a retrospective multicenter study.

Even though many studies have been published regarding return-to-sport (RTS) rates following arthroscopic Bankart repair (ABR), evidence regarding prognostic factors for which patients do not RTS is limited. The aim of this study was to identify prognostic factors that are associated with failure to RTS and failure to return to preinjury level of sport (RTPS) following primary ABR. The hypothesis was that prognostic factors for failure to RTS and failure to RTPS would be similar to those predisposing recurrence. A multicenter, retrospective case-control study including 6 Dutch hospitals was performed. Consecutive patients who underwent primary ABR between 2014 and 2019 were invited to participate and received a questionnaire. Sports participation was assessed before symptom onset, at 6 months postoperatively, and at final follow-up. Failure to RTS was defined as no return to any sport, and failure to RTPS was defined as no return to the same level (or a higher level) of sport. Prognostic factors for failure to RTS or failure to RTPS were identified using logistic regression. Covariates for the regression analysis were selected based on univariate analyses. This study included 318 patients with a mean follow-up period of 4.2 years (standard deviation, 1.8 years). Of these 318 patients, 26 (8.2%) did not RTS and 100 (31%) did not RTPS. Logistic regression analysis demonstrated that glenoid bone loss (odds ratio [OR], 1.09; 95% confidence interval [CI], 1.04-1.15; P=.001) and overhead use of the shoulder during work (OR, 3.77; 95% CI, 1.45-9.85; P=.007) were prognostic factors for failure to RTS. In addition, it showed that preoperative professional sports level (OR, 2.94; 95% CI, 1.07-8.05; P=.04) and preoperative body mass index (OR, 1.11; 95% CI, 1.01-1.21; P=.04) were prognostic factors for failure to RTPS. Repair of a bony Bankart lesion (OR, 0.35; 95% CI, 0.15-0.81; P=.02) and the presence of an anterior labral periosteal sleeve avulsion (ALPSA) (OR, 0.44; 95% CI, 0.20-0.97; P=.04) were identified as factors that facilitated RTPS. This study identified glenoid bone loss and overhead use of the shoulder during work to be associated with failure to RTS. Moreover, preoperative sports level and preoperative body mass index were found to be associated with failure to RTPS. In contrast, a bony Bankart lesion and an anterior labral periosteal sleeve avulsion (ALPSA) lesion facilitated RTPS. Future prospective studies are needed to confirm these factors and determine which part of the effect can be attributed to (failure of) surgical treatment or changes in behavior.
