Cutting balloon angioplasty on branch pulmonary artery stenosis in pediatric patients.

Catheter Cardiovasc Interv 2021 Jun 10. Epub 2021 Jun 10.

Pediatric Cardiology, Arkansas Children's Hospital, Little Rock, Arkansas, USA.

Objectives: To identify medium-term results following cutting balloon angioplasty (CBA) for branch pulmonary artery stenosis (PAS) and predictors of successful intervention.

Background: CBA has emerged as a successful alternative therapy for PAS resistant to conventional balloon angioplasty techniques but there is little information on medium and long-term outcomes.

Methods: This is a descriptive, single center, retrospective chart review of pediatric patients who underwent CBA for PAS at Arkansas Children's Hospital between May 2005 and December 2020. Read More

NF1 mutation drives neuronal activity-dependent initiation of optic glioma.

Nature 2021 Jun 26;594(7862):277-282. Epub 2021 May 26.

Department of Neurology, Washington University School of Medicine, St Louis, MO, USA.

Neurons have recently emerged as essential cellular constituents of the tumour microenvironment, and their activity has been shown to increase the growth of a diverse number of solid tumours. Although the role of neurons in tumour progression has previously been demonstrated, the importance of neuronal activity to tumour initiation is less clear-particularly in the setting of cancer predisposition syndromes. Fifteen per cent of individuals with the neurofibromatosis 1 (NF1) cancer predisposition syndrome (in which tumours arise in close association with nerves) develop low-grade neoplasms of the optic pathway (known as optic pathway gliomas (OPGs)) during early childhood, raising  the possibility that postnatal light-induced activity of the optic nerve drives tumour initiation.

A natural knockout of the MYO7A gene leads to pre-weaning mortality in pigs.

Anim Genet 2021 May 6. Epub 2021 May 6.

Topigs Norsvin Research Center, Beuningen, The Netherlands.

The pig breeding system provides a unique framework to study recessive defects and the consequence on the phenotype. We examined a commercial synthetic Duroc population for recessive defects and identified a haplotype on chromosome 9 significantly affecting pre-weaning mortality. To identify the causal variant underlying the mortality, we examined sequence data of four carrier animals and 21 non-carrier animals from the same population. Read More

Gap between flexion and extension ranges of motion: a novel indicator to predict the loss of cervical lordosis after laminoplasty in patients with cervical spondylotic myelopathy.

J Neurosurg Spine 2021 Apr 30:1-10. Epub 2021 Apr 30.

1Department of Orthopedic Surgery, Osaka Medical College, Takatsuki; and.

Objective: Kyphotic deformity resulting from the loss of cervical lordosis (CL) is a rare but serious complication after cervical laminoplasty (CLP), and it is essential to recognize the risk factors. Previous studies have demonstrated that a greater flexion range of motion (fROM) and smaller extension ROM (eROM) in the cervical spine are associated with the loss of CL after CLP. Considering these facts together, one can hypothesize that an indicator representing the gap between fROM and eROM (gROM) is highly useful in predicting postoperative CL loss. Read More

Effects of 8 years of growth hormone treatment on scoliosis in children with Prader-Willi syndrome.

Eur J Endocrinol 2021 May 21;185(1):47-55. Epub 2021 May 21.

Dutch Reference Center for Prader-Willi Syndrome, Rotterdam, The Netherlands.

Objective: Scoliosis is frequently seen in children with Prader-Willi syndrome (PWS). There is still concern that growth hormone (GH) treatment might increase the risk of onset or progression of scoliosis. Short-term data suggested no adverse effects of GH on scoliosis, but long-term effects of GH treatment on development of scoliosis in PWS are unknown. Read More

Outcomes of Vertical Expandable Prosthetic Titanium Ribs in Children With Early-Onset Scoliosis Secondary to Cerebral Palsy.

Cureus 2021 Mar 4;13(3):e13690. Epub 2021 Mar 4.

Pediatric Orthopaedic Surgery, Children's Hospital of Mississippi, Jackson, USA.

Purpose Patients who have neuromuscular scoliosis, such as cerebral palsy (CP), often develop spinal deformities that negatively impact quality of life. The vertical expandable prosthetic titanium rib (VEPTR) was designed for thoracic insufficiency syndrome (TIS), but it has also been utilized in patients with CP with restrictive lung disease and spine deformity. Few studies report on VEPTRs in neuromuscular scoliosis; however, none reports on their utilization specifically in patients with CP. Read More

Ehlers-Danlos syndrome-associated craniocervical instability with cervicomedullary syndrome: Comparing outcome of craniocervical fusion with occipital bone versus occipital condyle fixation.

J Craniovertebr Junction Spine 2020 Oct-Dec;11(4):287-292. Epub 2020 Nov 26.

Department of Neurosurgery, Hofstra School of Medicine, North Shore University Hospital, Manhasset, NY, USA.

Introduction: Ehlers-Danlos syndrome (EDS) predisposes to craniocervical instability (CCI) with resulting cranial settling and cervicomedullary syndrome due to ligamentous laxity. This study investigates possible differences in radiographic outcomes and operative complication rate between two surgical techniques in patients with EDS and CCI undergoing craniocervical fusion (CCF): occipital bone (OB) versus occipital condyle (OC) fixation.

Methods: A retrospective search of the institutional operative database between January 07, 2017, and December 31, 2019, was conducted to identify EDS patients who underwent CCF with either OB (Group OB) or OC (Group OC) fixation. Read More

Cytokine Release Syndrome Biology and Management.

Cancer J 2021 Mar-Apr 01;27(2):119-125

From the Division of Pediatric Hematology/Oncology, Department of Pediatrics.

Abstract: The successful application of chimeric antigen receptor (CAR) T cells for the treatment of relapsed and refractory B-cell malignancies has ushered in a new frontier for the immunotherapy of cancer. Despite its successes, CAR T-cell therapy presents several challenges. Cytokine release syndrome (CRS) triggered by robust and exponential CAR T-cell expansion is the most common adverse effect and may be severe or life-threatening. Read More

Report of a case of Cobb syndrome: multimodality imaging.

BJR Case Rep 2021 Feb 23;7(1):20200145. Epub 2020 Oct 23.

Department of Radiology, Kasr Al Ainy Hospital, Cairo, Egypt.

Cobb syndrome is a rare vascular disorder characterized by vascular skin lesions distributed in a dermatomal pattern, with corresponding muscular, osseous, paraspinal, and/or spinal vascular lesions occurring at the same body somite (metamere). We present a case of a 25-year-old man who presented with a history of right upper limb paresthesia followed by bilateral progressive upper and lower limb weakness and heaviness. Physical examination showed large cutaneous port wine stains on the right side of the chest, the nape, and along the whole right upper limb in a dermatomal distribution, with no corresponding limb hypertrophy or asymmetry.

Superior mesenteric artery syndrome: A rare complication of scoliosis corrective surgery.

J Orthop Surg (Hong Kong) 2020 Sep-Dec;28(3):2309499020945014

Department of Orthopaedic Surgery (NOCERAL), Faculty of Medicine, University of Malaya, Kuala Lumpur, Malaysia.

Superior mesenteric artery (SMA) syndrome is a rare but serious complication following scoliosis surgery. Early diagnosis and management are key factors for successful conservative treatment to avoid the need for emergency laparotomies which causes higher morbidity or even mortality. We report two adolescent idiopathic scoliosis patients with Cobb angle of 49° and 132°, respectively, and low body mass index who presented with SMA syndrome following posterior spinal fusion from T2 to L3 and were treated successfully with conservative management.

Monitoring Arteriovenous Malformation Response to Genotype-Targeted Therapy.

Pediatrics 2020 09;146(3)

Pediatrics, University of California San Francisco, San Francisco, California.

Arteriovenous malformations (AVMs) have recently been reported to have a high incidence of somatic KRAS mutations suggesting potential for treatment with mitogen-activated protein kinase inhibitors. In this case report, we describe genotype-targeted treatment of a KRAS mutant metameric AVM in a patient with Cobb syndrome using the mitogen-activated protein kinase inhibitor trametinib. Therapeutic response was monitored with phase-contrast magnetic resonance angiography to quantify AVM arterial inflow as an imaging biomarker. Read More
