BACKGROUND: Posteromedial and greater trochanteric fragments are a major cause of telescoping and medialization of the femoral shaft in an unstable intertrochanteric fracture. This leads to significant limb shortening, fracture collapse in varus position and implant failure, which can be prevented by trochanteric wiring in addition to dynamic hip screw (DHS) fixation. The purpose of our study is to assess the outcomes of DHS augmented with trochanteric wiring in unstable type A2 intertrochanteric fractures...

Kohler's disease is rare cause of foot pain and limping in the pediatric population. The exact etiology of Kohler's disease is unknown. It usually presents as sudden and unexplained foot pain and limping. We report a case of a 5-year-old male who presented to the Pediatric Emergency Department with foot pain and inability to bear weight for two days after overactivity and acute foot injury. The patient was eventually diagnosed with Kohler's disease (avascular necrosis of the navicular bone). Although Kohler's disease is not very common, it should be considered in the differential diagnosis of foot pain in the pediatric population, as it may prevent unnecessary tests and treatments...

A 4-year-old female was referred to pediatric orthopedic surgery for left leg pain and limping for 3 months following a motor vehicle collision. Recently, the patient's mother had noted left knee swelling and dragging of the left leg when walking. Past medical history was significant for hip dysplasia with slight leg length discrepancy. The patient was otherwise healthy. Physical examination was remarkable for left pre-patellar soft tissue fullness with normal range of motion. There was no warmth or tenderness...

INTRODUCTION: To the best of our knowledge, there has been no report regarding rheumatoid arthritis associated with spinal neuroarthropathy and combined double-level isthmic spondylolisthesis. Here, we report a rare case of spinal neuroarthropathy with double-level isthmic spondylolisthesis in a rheumatoid arthritis (RA) patient. A 56-year-old female patient under medical treatment for RA during the last 13 years presented aggravating radiating pain to her right lower extremity and a limping gait developed 4 months ago...

Conventional kinesin (kinesin-1) can walk on microtubule filaments in an asymmetric hand-over-hand manner, exhibiting a marked alternation in the mean dwell time in successive steps. Here, we study computationally the asymmetric stepping dynamics of the kinesin-1 homodimer, revealing its origin and providing quantitative explanations of the available experimental data. The alternation in the mean dwell time in successive steps arises from the alternation in the mechanochemical coupling ratio, which is in turn caused by the alternation in the slight variation of the stretched neck linker length...

When new motor learning changes the spinal cord, old behaviors are not impaired; their key features are preserved by additional, compensatory, plasticity. To explore the mechanisms responsible for this compensatory plasticity, we transected the spinal dorsal ascending tract (DA) before or after female rats acquired a new behavior -- operantly conditioned increase or decrease in the right soleus H-reflex - and examined an old behavior - locomotion. Neither DA transection nor H-reflex conditioning alone impaired locomotion...

This case report discusses the rare association of cerebral abscess related to conjunctivitis in an otherwise healthy child. A 6 year old boy presented with conjunctivitis was treated with topical antibiotics and resolved after a week. Conjunctival swab cultures grew MRSA. A month later he developed status epileptics and CT scans revealed a large cerebral abscess. He was treated with intravenous antibiotics which covered for MRSA, along with an incision and drainage for the cerebral abscess. Pus cultures grew MRSA...

Heterotopic ossification in soft tissue or muscle is rare in the pediatric and adolescent age group. Most cases are associated with musculoskeletal injury and trauma to the central nervous system. Here, we describe an adolescent patient without a history of trauma or lesions in the central nervous system who presented with a painful limp with limited motion of the left hip. Investigations indicated unusually large heterotopic ossification extending from the inner aspect of the ilium down to the anterior part of the hip, highly likely to have developed after an unrecognized periacetabular pyomyositis primarily involving the iliacus muscle...

Molecular heterogeneity between primary tumors (PTs) and synchronous resected liver metastasis in colorectal cancer (CRC) has potential relevance in treatment strategies. Next-generation sequencing (NGS) may be able to increase the chances of identifying multiple molecular driver alterations, calling for therapy. The aim of the present study was to evaluate mutations in PT and synchronous resected liver metastases for patients with Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) exon 2 wild-type metastatic (m)CRC who underwent chemotherapy (CT) featuring an anti-epidermal growth factor receptor (EGFR) monoclonal antibody...

In animals, foot-and-mouth disease (FMD) causes symptoms such as fever, limping and the development of blister spots on the skin and mucous membranes. RNA interference (RNAi) may be a novel way of controlling the FMD virus (FMDV), specifically by targeting its cognate receptor protein integrin β6. The present study used RNAi technology to construct and screen plasmids that expressed small interfering RNA molecules (siRNAs) specific for the integrin β6 subunit. Expression of green fluorescence protein from the RNAi plasmids was observed following transfection into porcine embryonic fibroblast (PEF) cells, and RNAi plasmids were screened using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis...

REVIEW
David M Peck, Lisa M Voss, Tyler T Voss
Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in adolescents, occurring in 10.8 per 100,000 children. SCFE usually occurs in those eight to 15 years of age and is one of the most commonly missed diagnoses in children. SCFE is classified as stable or unstable based on the stability of the physis. It is associated with obesity, growth spurts, and (occasionally) endocrine abnormalities such as hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism. Patients with SCFE usually present with limping and poorly localized pain in the hip, groin, thigh, or knee...

Pediatric limp is a relatively common condition in primary care and can be challenging to diagnose and manage. Common causes of painful pediatric limp include transient synovitis, septic arthritis, osteomyelitis, and trauma. The authors present the case of an 11-year-old girl with a painful limp and anterior ankle pain of unclear origin. Osteopathic structural examination revealed a somatic dysfunction known as continuum distortion, 1 of 6 fascial alterations identified in the fascial distortion model. Myofascial release was applied, providing rapid, complete resolution of symptoms...
