OBJECTIVE
To report the technique and outcome of proximal ulnar autograft transplantation to achieve ipsilateral radial lengthening in a dog with premature closure of both proximal and distal radial physes.
STUDY DESIGN
Case report.
ANIMALS
An 8-month-old female spayed Border Collie.
METHODS
The dog was presented for a grade III/IV left thoracic limb lameness localized to the elbow. Orthogonal radiographs of both forelimbs revealed a 7% length deficit of the left radius and elbow subluxation indices indicative of left elbow incongruity due to suspect premature closure of both radial physes. Radial lengthening consisted of a proximal ulnar ostectomy, a radial osteotomy, and transplantation of the ulnar autograft into the radial osteotomy site secured with an eight-hole dynamic compression plate. Orthopedic examinations were conducted at 2 weeks, 4 weeks, and 3 years postoperatively. Radiographic examinations were completed preoperatively, immediately postoperatively, and at 4 weeks and 3 years postoperatively.
RESULTS
Lameness improved with a grade II/IV lameness at 4 weeks postoperatively and complete resolution at 3 years postoperatively. Radiographic examination at 4 weeks showed persistent radial lengthening of 1 cm, and a decreased humeroradial index (HRI), humeroulnar index (HUI), and radioulnar index (RUI) compared with preoperative values. At the 3 year examination, the HRI and HUI had increased indicating progression of elbow incongruity. The patient remained clinically unaffected.
CONCLUSION
In dogs with radial shortening and elbow incongruity, use of an ipsilateral proximal ulnar autograft with rigid internal fixation can be an effective treatment for radial lengthening to improve elbow congruity and resolve lameness.

BACKGROUND
Neither radiological phenotypic characteristics nor reconstruction CT scan has been used to study the early anatomical disruption of the cranial bone in children with the so-called idiopathic type of West syndrome.
MATERIAL AND METHODS
The basic diagnostic measures and the classical antiepileptic treatments were applied to these children in accordance with the conventional protocol of investigations and treatment for children with West syndrome. Boys from three unrelated families were given the diagnosis of the idiopathic type of West syndrome, aged 7, 10 and 12 years old. Parents underwent extensive clinical examinations. Three parents (age range of 28-41 year) were included in this study. All children showed a history of intellectual disabilities, cryptogenic epileptic spasms and fragmented hypsarrhythmia. These children and their parents were referred to our orthopedic departments because of variable skeletal deformities. Variable forms of skeletal deformities were the motive for the families to seek orthopedic advice. A constellation of flat foot, torticollis and early-onset osteoarthritis were observed by the family doctor. Apparently, and from the first clinical session in our practice, we felt that all these children are manifesting variable forms of abnormal craniofacial contour. Thereby, we immediately performed detailed cranial radiological phenotypic characterization of every affected child, as well as the siblings and parents, and all were enrolled in this study. All affected children underwent whole-exome sequence analysis.
RESULTS
The craniofacial phenotype of all children revealed apparent developmental anatomical disruption of the cranial bones. Palpation of the skull bones showed unusual palpable bony ridges along different sutural locations. A 7-year-old child showed abnormal bulging over the sagittal suture, associated with bilateral bony ridges over the squamosal sutures. AP skull radiograph of a 7-year-old boy with West syndrome showed facial asymmetry with early closure of the metopic suture, and other sutures seemed ill-defined. A 3D reconstruction CT scan of the skull showed early closure of the metopic suture. Another 3D reconstruction CT scan of the skull while the patient was in flexion showed early closure of the squamosal sutures, pressing the brain contents upward, causing the development of a prominent bulge at the top of the mid-sagittal suture. A reformatted 3D reconstruction CT scan confirmed the bilateral closure of the squamosal suture. Examination of the parents revealed a similar skull radiographic abnormality in his mother. A 3D reformatted frontal cranial CT of a 35-year-old mother showed early closure of the metopic and sagittal sutures, causing a mid-sagittal bony bulge. A 10-year-old boy showed an extremely narrow frontal area, facial asymmetry and a well palpable ridge over the lambdoid sutures. A 3D axial reconstruction CT scan of a 10-year-old boy with West syndrome illustrated the asymmetry of the posterior cranial bones along the lambdoid sutures. Interestingly, his 28-year-old mother has been a client at the department of spine surgery since she was 14 years old. A 3D reconstruction CT scan of the mother showed a noticeable bony ridge extending from the metopic suture upwards to involve the sagittal suture (red arrow heads). The black arrow shows a well demarcated bony ridge over the squamosal suture. A 3D reconstruction CT scan of the skull and spine showed the thick bony ridge of the metopic and the anterior sagittal as well as bilateral involvement of the squamosal, causing apparent anterior narrowing of the craniofacial contour. Note the lumbar scoliosis. A 12-year-old boy showed brachycephaly. A lateral skull radiograph of a 12-year-old boy with West syndrome showed premature sutural fusion, begetting an abnormal growth pattern, resulting in cranial deformity. The nature of the deformity depends on which sutures are involved, the time of onset and the sequence in which individual sutures fuse. In this child, brachycephalic secondary to craniosynostosis, which occurred because of bilateral early ossification of the coronal sutures, led to bi-coronal craniosynostosis. Thickened frontal bones and an ossified interclinoid ligament of the sella turcica were encountered. The lateral skull radiograph of a 38-year-old mother with a history of poor schooling achievements showed a very similar cranial contour of brachycephaly, thickening of the frontal bones and massive ossification of the clinoid ligament of the sella turcica. Maternal history revealed a history of multiple spontaneous miscarriages in the first trimester of more than five times. Investigating his parents revealed a brachycephalic mother with borderline intelligence. We affirm that the pattern of inheritance in the three boys was compatible with the X-linked recessive pattern of inheritance. Whole-exome sequencing showed non-definite phenotype/genotype correlation.
CONCLUSIONS
The aim of this study was sixfold: firstly, to refute the common usage of the term idiopathic; secondly, we feel that it could be possible that West syndrome is a symptom complex rather than a separate diagnostic entity; thirdly, to further detect the genetic carrier, we explored the connection between the cranial bones in children with West syndrome with what has been clinically observed in their parents; fourthly, the early life anatomical disruptions of the cranial bones among these children seem to be heterogeneous; fifthly, it shows that the progressive deceleration in the development of this group of children is highly connected to the progressive closure of the cranial sutures; sixthly, we affirm that our findings are novel.

INTRODUCTION
Blount disease is a disorder causing three proportions of deformity, including varus deformity, procurvatum deformity, and internal tibial rotational deformity. The standardized treatment remains controversial despite extensive reviews. The application of Ilizarov external fixators for circumspect corrections is established. The SCARE 2023 criteria have been followed in reporting the case report.
CASE PRESENTATION
We present the case of a nine-year-old girl who's complaining about bowing on both of her knees. From the examination, we found that the metaphyseodiaphyseal angle of both knees was 50 degrees. On the right knee, there is 125 degrees of procurvatum deformity and 115 degrees of deformity on the left knee. After performing deformity correction with the Ilizarov application, there's clinical improvement in the patient.
CLINICAL DISCUSSION
Some experts advise using physeal distraction to manage the deformity in order to achieve correction. The limited popularity of physeal distraction technique may be attributed to the risks of premature closure of the growth plate that we manage to avoid. The Ilizarov frame provides maximum adjustability for aligning all planes, making it suitable for treating severe deformities. Secure fixation, improved patient mobility, being able to assess patient alignment in a functional standing position, and precision.
CONCLUSION
Acute correction and fixation using circular frames as a treatment option for Blount disease show positive outcomes without any significant complications.

INTRODUCTION
Recent liquid adhesive skin closure systems with a mesh patch and a 2-octyl cyanoacrylate liquid formula have shown promising results in total joint arthroplasty (TJA). Chemical accelerators are typically included to promote the rapid polymerization of 2-octyl cyanoacrylate. The goal of the study is to distinguish designs and wound complication differences between two similar systems.
METHODOLOGY
An eighteen-week retrospective study was conducted from July to December 2023, including 207 total hip arthroplasty (THA) and 212 total knee arthroplasty (TKA) cases from four attending surgeons at one institution that used one of two dressing designs. Both dressings had a 2-octyl cyanoacrylate liquid adhesive formula that applied topically to a polyester-based mesh overlaying the wound. Mesh A (used in 274 cases) included an accelerator, a quaternary ammonium salt, on the mesh patch, whereas Mesh B (used in 145 cases) included a similar accelerator within the adhesive applicator.
RESULTS
Wound complications (3.2 versus 7.6%; X = 3.86; df = 1; P = 0.049), early periprosthetic joint infections (PJI) (0 versus 2.8%; X = 7.63; df = 1; P = 0.006), and 90-day reoperations for wound complications (0.4 versus 3.4%; X = 6.39; df = 1; P = 0.011) were significantly lower in patients who received Mesh A versus B, respectively. There was no difference in superficial surgical site infections (SSI) (0.7 versus 0%; X = 1.06; df = 1; P = 0.302) or allergy rates (3.3 versus 4.1%; X = 0.12; df = 1; P = 0.655) between Mesh A and B.
CONCLUSION
We observed significantly different performance in wound complications, early postoperative PJI, and 90-day reoperation between the two designs. Having the accelerator in the applicator rather than on the mesh patch, may lead to premature polymerization before bonding appropriately with the mesh to create the desired wound closure and seal.

Endoscopic through-the-scope clips (TTSC) are used for hemostasis and closure. We documented the performance of a new TTSC with anchor prongs. We conducted a prospective case series of the new TTSC in 50 patients with an indication for endoscopic clipping at three hospitals in the United States and Canada. Patients were followed for 30 days after the index procedure. Outcomes included defect closure and rate of serious adverse events (SAEs) related to the device or procedure. Fifty patients had 56 clipping procedures. Thirty-four procedures were clipping after endoscopic mucosal resection (EMR) in the colon (33) or stomach (1), 16 after polypectomy, two for hemostasis of active bleeding, and one each for fistula closure, per-oral endoscopic myotomy mucosal closure, or anchoring a feeding tube. Complete defect closure was achieved in 32 of 33 colon EMR defects and 21 of 22 other defects. All clips were placed per labeled directions for use. In 41 patients (82.0%), prophylaxis of delayed bleeding was reported as an indication for endoscopic clipping. There were three instances of delayed bleeding. There were no device-related SAEs. The only technical difficulty was one instance of premature clip deployment. A novel TTSC with anchor prongs showed success in a range of defect closures, an acceptable safety profile, and low incidence of technical difficulties.

American Journal of Veterinary Research Jun 2024To determine if photobiomodulation causes a premature release of liposomal bupivacaine (LB) suspensions.
OBJECTIVE
To determine if photobiomodulation causes a premature release of liposomal bupivacaine (LB) suspensions.
ANIMALS
A 25-kg mixed breed dog cadaver euthanized for reasons unrelated to this study.
METHODS
In September 2022, a proximomedial tibial incision was made in a dog cadaver, and a tibial plateau leveling osteotomy plate was implanted. A stab incision was made one-half inch distal to the incision, and a tunnel to the plate was created prior to closure of the primary wound. A 3-cc anal sac catheter was advanced through the distal incision until the bulb rested against the face of the plate. Seven treatment groups of treatment power (watts) and total energy (joules/cm2) were defined as: A, 0.5 W, 2.0 J/cm2; B, 0.5 W, 4.0 J/cm2; C, 0.5 W, 6.0 J/cm2; D, 1.0 W, 2.0 J/cm2; E, 1.0 W, 4.0 J/cm2; F, 1.0 W, 6.0 J/cm2; and sham, 0.0 W, 0.0 J/cm2. Ten samples per group of 2 mL of LB were infused into a new catheter and treated percutaneously with a class 3b laser. All samples remained in the catheter for 12 seconds to reflect the longest treatment time. Post-treatment free bupivacaine concentrations were identified with high-performance liquid chromatography.
RESULTS
The median free bupivacaine concentration was reported as: sham, 1.89 mg/mL; A, 1.93 mg/mL; B, 2.01 mg/mL; C, 2.05 mg/mL; D, 1.92 mg/mL; E, 2.03 mg/mL; and F, 2.00 mg/mL. There were no differences in median free bupivacaine concentrations between groups (P = .988).
CLINICAL RELEVANCE
Concurrent LB and photobiomodulation are recommended during the postoperative period. The results of this proof-of-concept study suggest that concurrent use of LB and photobiomodulation may be safe, but in vivo studies at similar and stronger photobiomodulation settings are warranted.

A 4-month-old full-term female presented with growth faltering associated with progressive feeding difficulty, rash, abdominal distension, and developmental delays. She was found to have disconjugate gaze, abnormal visual tracking, mixed tone, bruising, and splenomegaly on examination. Initial workup was notable for thrombocytopenia and positive cytomegalovirus (CMV) immunoglobulin G and immunoglobulin M antibodies. She initially presented to the infectious diseases CMV clinic, where she was noted to have severe malnutrition, prompting referral to the emergency department for hospital admission to optimize nutrition with nasogastric tube feeding and facilitate additional evaluation. An active CMV infection with viruria and viremia was confirmed, but elements of her presentation and workup including brain magnetic resonance imaging were not consistent with isolated CMV infection. To avoid premature diagnostic closure, a multidisciplinary workup was initiated and ultimately established her diagnosis.

OBJECTIVE
Acetaminophen (APAP) is an alternative to indomethacin and ibuprofen for treatment of patent ductus arteriosus (PDA). The side effect profile of non-steroidal anti-inflammatory drugs (NSAIDs) presents enteral feeding safety concerns; however, the safety of enteral feeding on APAP is largely unknown. Optimal feeding strategies during pharmacological PDA treatment are unknown, leading to practice variation. This study aims to assess the incidence of adverse gastrointestinal (GI) outcomes in neonates treated with APAP for PDA closure while receiving enteral feedings.
METHODS
Single-center retrospective cohort study of 59 extremely low birth weight (ELBW), premature neonates who received APAP for PDA treatment divided into Low Volume (LV; ≤ 20 mL/kg/day) and High Volume (HV; > 20 mL/kg/day) enteral feeding groups. The primary outcome was the incidence of any suspected or confirmed necrotizing enterocolitis (NEC). Timing of nutrition milestones, parenteral nutrition (PN) days, and adverse outcomes (feeding intolerance, liver dysfunction, death prior to discharge) were evaluated.
RESULTS
The incidence of suspected or confirmed NEC was 19.5% in the LV group and 13.3% in the HV group (p = 0.593). The HV group reached full feeds 6 days sooner (18 vs 24 days, p = 0.024) and had fewer PN days (17 vs 23.5 days, p = 0.044) with no difference in adverse outcomes.
CONCLUSIONS
Provision of > 20 mL/kg/day of enteral feeds during APAP treatment of PDA decreased time to full feeds and PN days compared to trophic feedings (≤ 20 mL/kg/day) with no difference in adverse GI outcomes. Continuing enteral feeding during APAP PDA treatment appears safe while improving achievement of nutritional milestones.

IMPORTANCE
The binary classification of spina bifida lesions as myelomeningocele (with sac) or myeloschisis (without sac) belies a spectrum of morphologies, which have not been correlated to clinical characteristics and outcomes.
OBJECTIVE
To characterize spina bifida lesion types and correlate them with preoperative presentation and postoperative outcomes.
DESIGN
Secondary analysis of images and videos obtained during fetoscopic spina bifida repair surgery from 2020-2023.
SETTING
Fetal surgery was performed at a quaternary care center.
PARTICIPANTS
A prospective cohort of patients referred for fetal spina bifida underwent fetoscopic repair under an FDA-approved protocol. Of 60 lesions repaired, 57 had available images and were included in the analysis.
INTERVENTIONS OR EXPOSURES
We evaluated lesion morphology on high-resolution intraoperative images and videos to categorize lesions based on placode exposure and nerve root stretching.
MAIN OUTCOMES AND MEASURES
The reproducibility of the lesion classification was assessed via Kappa interrater agreement. Preoperative characteristics analyzed include ventricle size, tonsillar herniation level, lower extremities movement, and lesion dimensions. Outcomes included surgical time, need for patch for skin closure, gestational age at delivery, preterm premature rupture of membranes (PPROM), and neonatal cerebrospinal fluid (CSF) diversion.
RESULTS
We distinguished five lesion types that differ across a range of sac sizes, nerve root stretching, and placode exposure, with 93% agreement between examiners (p<0.001). Fetal characteristics at preoperative evaluation differed significantly by lesion type, including lesion volume (p<0.001), largest ventricle size (p=0.008), tonsillar herniation (p=0.005), and head circumference (p=0.03). Lesion level, talipes, and lower extremities movement did not differ by type. Surgical and perinatal outcomes differed by lesion type, including need for patch skin closure (p<0.001), gestational age at delivery (p=0.01), and NICU length of stay (p<0.001). PPROM, CSF leakage at birth, and CSF diversion in the NICU did not differ between lesion groups. Linear regression associated severity of ventriculomegaly with lesion type, but not with tonsillar herniation level.
CONCLUSIONS AND RELEVANCE
There is a distinct phenotypic spectrum in open spina bifida with differential baseline presentation and outcomes. Severity of ventriculomegaly is associated with lesion type, rather than tonsillar herniation level. Our findings expand the classification of spina bifida to reveal a spectrum that warrants further study.

Randomized Controlled Trial
BACKGROUND
The effect of dual systemic antibiotic therapy against Pseudomonas aeruginosa in patients with pre-existing lung disease is unknown. To assess whether dual systemic antibiotics against P. aeruginosa in outpatients with COPD, non-cystic fibrosis (non-CF) bronchiectasis, or asthma can improve outcomes.
METHODS
Multicenter, randomised, open-label trial conducted at seven respiratory outpatient clinics in Denmark. Outpatients with COPD, non-CF bronchiectasis, or asthma with a current P. aeruginosa-positive lower respiratory tract culture (clinical routine samples obtained based on symptoms of exacerbation not requiring hospitalisation), regardless of prior P. aeruginosa-status, no current need for hospitalisation, and at least two moderate or one hospitalisation-requiring exacerbation within the last year were eligible. Patients were assigned 1:1 to 14 days of dual systemic anti-pseudomonal antibiotics or no antibiotic treatment. Primary outcome was time to prednisolone or antibiotic-requiring exacerbation or death from day 20 to day 365.
RESULTS
The trial was stopped prematurely based in lack of recruitment during the COVID-19 pandemic, this decision was endorsed by the Data and Safety Monitoring Board. Forty-nine outpatients were included in the study. There was a reduction in risk of the primary outcome in the antibiotic group compared to the control group (HR 0.51 (95%CI 0.27-0.96), p = 0.037). The incidence of admissions with exacerbation within one year was 1.1 (95%CI 0.6-1.7) in the dual antibiotic group vs. 2.9 (95%CI 1.3-4.5) in the control group, p = 0.037.
CONCLUSIONS
Use of dual systemic antibiotics for 14 days against P. aeruginosa in outpatients with chronic lung diseases and no judged need for hospitalisation, improved clinical outcomes markedly. The main limitation was the premature closure of the trial.
