BACKGROUND: Forearm compartment syndrome in the pediatric population can lead to severe functional disability. Although it is known that earlier presentation with decompression leads to better outcomes, it is not known when presentation post-injury leads to significant loss of function requiring microsurgical intervention. AIM: To describe the rate of microsurgical reconstruction after forearm compartment syndrome in pediatric patients as related to timing of presentation...

Intra-abdominal hypertension (IAH) is highly prevalent in critically ill patients admitted to the intensive care unit and is associated with an increased morbidity and mortality. The present study investigated whether femoral venous pressure (FVP) can be used as a surrogate parameter for intra-abdominal pressure (IAP) measured via the bladder in IAH grade II (IAP <20 mmHg) or grade III (IAP ≥20 mmHg). This was a single-centre prospective study carried out in a tertiary adult intensive care unit. IAP was measured via the bladder with a urinary catheter with simultaneous recording of the FVP via a femoral central line...

Myelin is a specialized structure of the nervous system that both enhances electrical conductance and insulates neurons from external risk factors. In the central nervous system, polarized oligodendrocytes form myelin by wrapping processes in a spiral pattern around neuronal axons through myelin-related gene regulation. Since these events occur at a distance from the cell body, post-transcriptional control of gene expression has strategic advantage to fine-tune the overall regulation of protein contents in situ...

A 33-year-old elite female runner presented to a tertiary care sports medicine clinic with a 2-year history of progressive anterior thigh and circumferential leg pain with associated foot paresthesias brought on by high-intensity running. She had both external iliac artery vasospasm and chronic exertional compartment syndrome. External iliac artery vasospasm is a rare cause of exertional leg pain, particularly in the running population. This case highlights the unique features of this condition, addresses the multidisciplinary approach that led to the accurate diagnoses, and demonstrates that more than 1 etiology for exertional leg pain can coexist in an athlete...

BACKGROUND: Although the recommended treatment for Gartland types I and III supracondylar humeral fractures is well-established, the optimal treatment for type II fractures without rotational malalignment remains controversial, involving circumferential casting or closed reduction and pinning. Our institution uses pronated flexion-taping for Gartland type IIA fractures. This theoretically removes external pressure secondary to circumferential casting, potentially decreasing risks of compartment syndrome and mitigating loss of reduction with extension while maintaining optimal flexion position for reduction...

Bengt Rippe, Carl M Öberg
The turnover of albumin is increased in both peritoneal dialysis (PD) and hemodialysis (HD) due to increased external losses, normally leading to compensatory increases in the hepatic albumin synthesis. The normal rate of albumin synthesis is on the order of 12 g/day corresponding to an equally large albumin fractional catabolic rate of ~4% daily. Most albumin catabolism is assumed to occur in the endothelium, but there is also renal and hepatic catabolism and leakage into the gastrointestinal tract. In PD the daily losses are on the order of 5 g/day...

OBJECTIVE: To describe a novel coronal osteotomy of the external facet of the patella, and to evaluate if the outcomes of the treatment of lateral knee compartment syndrome (LKCS) with this osteotomy, combined with the release of the external lateral retinaculum, are better than the isolated lateral retinacular release. MATERIAL AND METHODS: A prospective study with a 2 year follow up that included 70 patients diagnosed with LKCS, distributed into 2 groups. The first group included 50 patients on whom the lateral retinacular release combined with osteotomy was performed, and a second group on whom an isolated retinacular release was performed...

Background: Dislocation fractures of the tibial plateau often lead to functional restrictions and subjective complaints from the patients. Besides functional and radiological results, criteria to determine the quality of life are of increasing importance. Intermediate term restriction in quality of life was evaluated and correlated with objective radiological results in patients with Moore type V dislocation fracture of the tibial plateau. Patients and Methods: From 2003 to 2012, a multicentre retrospective cohort study in three hospitals was used to register 36 patients with 38 Moore type V dislocation fractures of the tibial plateau...

A 73-year-old man with chronic kidney disease stage G5 was admitted to our hospital because of a worsening kidney dysfunction. He had undergone prosthetic valve replacement of the mitral valve 5 years previously and was currently taking warfarin. He showed excessive anticoagulation on admission, with a prothrombin time-international normalized ratio (PT-INR) of 3.91. The use of warfarin was ceased and PT-INR decreased to 2.1. Since the patient would need renal replacement therapy, he underwent arteriovenous fistula surgery for hemodialysis access on day 16...

OBJECTIVES: The authors have identified a subset of bicondylar tibial plateau fractures with a hyperextension varus deformity (HEVBTP). The radiographic hallmarks of this pattern are (1) sagittal plane malalignment with loss of the normal posterior slope of the tibial plateau, (2) tension failure of the posterior cortex, (3) compression of the anterior cortex, and (4) varus deformity in the coronal plan. The purpose of this study was to describe this fracture pattern, to compare the associated injuries with non-HEVBTP fractures, and to suggest treatment strategies that may allow for improved reduction and stabilization...

Tibial shaft fractures are common injuries in the pediatric population, and can be treated conservatively the vast majority of the time. Yet, it is important to recognize that open and/or unstable tibial shaft fractures represent a different entity. Rigid intramedullary devices are generally contraindicated because of the skeletal immaturity of these patients, and external fixation is associated with a high complication rate. As a result, flexible nailing is being utilized with increasing frequency. It is essential for the clinician to understand the pearls and pitfalls associated with the utilization of these flexible nails; particularly in regards to their immediate use in the context of open fractures and the risk of compartment syndrome postoperatively after fixation...

Orbital extension of subgaleal hematoma is rare. This report describes the case of an otherwise healthy 10-year-old girl who developed delayed contralateral proptosis and external ophthalmoplegia after relatively minor right-sided forehead trauma. She was found to have bilateral subgaleal hematomas communicating with a left superior subperiostial orbital hematoma. Over the course of 2 days, she developed an orbital compartment syndrome requiring emergent canthotomy and cantholysis, followed by surgical incision and drainage of her scalp hematoma without orbitotomy...

PURPOSE: Risperidone is a second-generation antipsychotic agent commonly used in the treatment of ~ 31.1% of schizophrenia patients in China, it is the most commonly-prescribed antipsychotic agent. Despite the abundant use of risperidone, population pharmacokinetic-pharmacodynamic models of risperidone have not been performed in Chinese schizophrenia patients. The objective of this study was to develop a population pharmacokinetic-pharmacodynamic (PopPK/PD) model to describe the PK behavior and efficacy of risperidone and 9-hydroxy-risperidone (active metabolite) in Chinese patients...

BACKGROUND: Well-leg compartment syndrome (WLCS) is one of the catastrophic complications related to prolonged surgical procedures performed in the lithotomy position, using a knee-crutch-type leg holder (KCLH) system, to support the popliteal fossae and calf regions. Obesity has been implicated as a risk factor in the lithotomy position-related WLCS during surgery. In the present study, we investigated the relationship between the external pressure (EP) applied to the calf region using a KCLH system in the lithotomy position and selected physical characteristics...

Toshihiro Kikuchi, Hiroyuki Maeda
Two cases of compartment syndrome of the lower extremities occurring during surgery for gynecological malignancies are reported. In addition to the risk from being in the lithotomy position for over 4 h, these two cases were believed to have been caused by the combined use of a disposable wound retractor and abdominal retractors to secure the operative field. This conclusion is based on the fact that an abrupt increase in partial pressure of end-tidal CO2 (ETCO2) was observed when wound drapes and abdominal retractors were removed approximately 4 h after the start of surgery...

BACKGROUND: Idiopathic and therapy resistant uveitis especially of unclear origin, is a diagnostic challenge for ophthalmologists. Metastases to the anterior chamber or vitreous body can occasionally mimic the clinical picture of uveitis, a variant on the usual lymphomatous masquerade syndrome. The underlying pathological pathways leading to the metastatic spread of tumor cells within the fluid compartments of the eye remain unclear. CASE REPORT: We present an unusual case of vitreous metastases to the right eye of a patient in whom an underlying primary malignancy was unknown...

BACKGROUND: Proximal tibia fractures with compartment syndrome present a challenge for orthopedic surgeons. More often than not these patients are subjected to multiple surgeries and are complicated by infection osteomyelitis and poor rehabilitation. There is no consensus in the management of these fractures. Most common mode is to do early fasciotomy with external fixation, followed by second stage definitive fixation. We performed a retrospective study of proximal tibia fractures with impending compartment syndrome treated by single stage fasciotomy and internal fixation...

REVIEW
Robert H Boyce, Keerat Singh, William T Obremskey
Acute knee dislocations are an uncommon injury that can result in profound consequences if not recognized and managed appropriately on presentation. Patients presenting with knee pain in the setting of high- or low-energy trauma may have sustained a knee dislocation that spontaneously reduced. Prompt reduction of the dislocated knee and serial neurovascular examinations are paramount. Damage to the popliteal artery is a common associated injury that can be diagnosed on physical examination using ankle brachial indices (ABIs), CT angiography, or standard angiography...

INTRODUCTION: Autism is diagnosed in numerous genetic and genomic developmental disorders associated with an overlap in high-risk genes and loci that underlie intellectual disability (ID) and epilepsy. The aim of this stereological study of neuronal soma volume in 25 brain structures and their subdivisions in eight individuals 9 to 26 years of age who were diagnosed with chromosome 15q11.2-13.1 duplication syndrome [dup(15)], autism, ID and epilepsy; eight age-matched subjects diagnosed with autism of unknown etiology (idiopathic autism) and seven control individuals was to establish whether defects of neuronal soma growth are a common denominator of developmental pathology in idiopathic and syndromic autism and how genetic modifications alter the trajectory of neuronal soma growth in dup(15) autism...
