Common injuries of the athlete's hand.

Hand injuries are among the most frequent accidents seen in sports medicine. All too commonly they are considered trivial since the athlete may continue to participate actively and neglect his injury. The consequent delay in diagnosis and proper treatment may result in long-standing or even permanent disability. This paper describes the more commonly encountered hand injuries, their diagnosis and their optimal treatment. Included are soft-tissue injuries, ligamentous injuries, fractures and tendon avulsions. The basic principles applicable to skeletal and soft-tissue trauma of the hand, which physicians at all levels of sports medicine may encounter, are stressed.     

Reconstruction of the burned hand

This article summarizes the initial management of acute burn injuries to the hand, in addition to treatment and reconstructive options. The goal of treatment for a burn injury to the hand is primarily a functional hand. This is best achieved by appropriate early treatment, the right selection from a wide range of possible reconstructive procedures, and focused occupational hand therapy.

Physical medicine for injured hands

The functional concepts of treatment of the injured hand by use of the various modalities of physical medicine, including heat, massage, electrical stimulation, passive exercises, active exercises, occupational therapy and splints are discussed. Immobilization is often necessary to correct anatomical injuries. Mobilization activities using physical medicine are just as necessary to correct functional deficiencies of the hand occurring either from the injury or the enforced immobilization following an injury.     

The role of calcium ions in freezing injuries of winter oilseed rape leaves. Effects of calcium channel blockers and mimesis by calcium ionophore

Calcium ionophore A23187 allowing for a calcium ion influx from an apoplast to a cytoplasm, mimicked symptoms of the frost-induced injuries in winter oilseed rape leaves, as estimated by the conductivity method. Both calcium ionophore and freezing treatment induced degradation of phosphatidylcholine. On the other hand lanthanum and gadolinum ions as well as verapamil, the inhibitors of calcium ion channels, decreased the degree of the frost-induced injuries. Lanthanum ions prevented the frost-induced degradation of PC. It is proposed that freezing alters the functioning of calcium ion channels which results in calcium ion influx into a cytosol. This in turn may lead to a degradation of cell membranes.     

Resolution of systemic complications in Schistosoma mansoni-infected mice by concomitant treatment with praziquantel and Schisandrin B

Schistosomiasis is a tropical parasitic disease, in which the major clinical manifestation includes hepatosplenomegaly, portal hypertension, and organs fibrosis. Clinically, treatment of schistosomiasis involves the use of praziquantel (PZQ) and supportive care, which does not improve the patient’s outcome as liver injuries persist. Here we show the beneficial effects of using PZQ in combination with Schisandrin B (Sch B). Concomitant treatment with PZQ and Sch B resulted in a significant improvement of hepatosplenomegaly and fibrosis, compared with single-agent treatment. We also demonstrated that PZQ-Sch B treatment ameliorates injuries in the lungs and intestine better than the sole use of PZQ or Sch B. In addition, PZQ-Sch B treatment improves the survival of S. mansoni-infected mice, and the treatment combination yields better therapeutic outcomes, as indicated by a partial improvement in neurological function. These results were accompanied by a reduction in neurological injuries. Collectively, we suggest that PZQ-Sch B concomitant therapy may be useful to alleviate schistosomiasis-associated liver injuries and prevent systemic complications.     

6. Changing concepts in the diagnosis and treatment of closed renal injuries.

Direct force is responsible for all closed kidney injuries except those involving the pedicle. Underlying parenchymal disease strongly predisposes the kidney to injury. Accurate diagnosis is crucial to rational treatment, and this is accomplished by infusion pyelography, angiography, retrograde pyelography and scanning. Treatment of kidney injuries has classically been conservatives, except when the clinical course or the nature of pre-existing diseases make an operation essential, but the current trend is towards more aggressive surgical treatment. This applies not only to pedicle injuries but also to major parenchymal trauma, and it is rendered feasible by precise diagnosis and improved surgical technique.     

Monkey models of recovery of voluntary hand movement after spinal cord and dorsal root injury

The hand is unique to the primate and manual dexterity is at its finest in the human (Napier 1980), so it is not surprising that cervical spinal injuries that even partially block sensorimotor innervation of the hand are frequently debilitating (Anderson 2004). Despite the clinical need to understand the neuronal bases of hand function recovery after spinal and/or nerve injuries, relatively few groups have systematically related subtle changes in voluntary hand use following injury to neuronal mechanisms in the monkey. Human and macaque hand anatomy and function are strikingly similar, which makes the macaque the favored nonhuman primate model for the study of postinjury dexterity. In this review of monkey models of cervical spinal injury that have successfully related voluntary hand use to neuronal responses during the early postinjury months, the focus is on the dorsal rhizotomy (or dorsal rootlet lesion) model developed and used in our laboratory over the last several years. The review also describes macaque monkey models of injuries to the more central cervical spine (e.g., hemisection, dorsal column) that illustrate methods to assess postlesion hand function and that relate it to neurophysiological and neuroanatomical changes. Such models are particularly important for understanding what the sensorimotor pathways are capable of, and for assessing the outcome of therapeutic interventions as they are developed.     

急性脊髓损伤的药物治疗进展概况

脊髓损伤(spinal cord injury,SCI)是临床上常见的一种创伤性疾病。随着社会的发展呈现上升的趋势,其来源主要有交通事故,工伤,坠落伤,暴力伤,运动损伤,积累性损伤等。传统的手术治疗是围绕脊柱的骨性结构进行椎管减压、脊柱稳定性的重建,并不能解决瘫痪的主要原因-脊髓损伤问题,预后并不理想。近年来国内外学者都在对SCI进行深入研究,想要找到SCI的根本机制,从而能针对性的研究出能改变SCI患者预后的药物。本文就对脊髓损伤目前的常用治疗药物做一篇综述。     

Treatment of Infertile Patients with Adequate or Slightly Diminished Endogenous Estrogen with a Lack of LH Surge

Pressure gun injection injuries are becoming increasingly common. Their effect on the fingers and hands, especially when improperly managed, can be devastating. Therefore it is important to review features, clinical course, anatomic distribution and operative management of such injuries. If a useful hand and fingers are to be attained, rapid and thorough decompression and debridement of these injuries are essential.     

The overexpression of RBM3 alleviates TBI‐induced behaviour impairment and AD‐like tauopathy in mice

The therapeutic hypothermia is an effective tool for TBI‐associated brain impairment, but its side effects limit in clinical routine use. Hypothermia up‐regulates RNA‐binding motif protein 3 (RBM3), which is verified to protect synaptic plasticity. Here, we found that cognitive and LTP deficits, loss of spines, AD‐like tau pathologies are displayed one month after TBI in mice. In contrast, the deficits of LTP and cognitive, loss of spines and tau abnormal phosphorylation at several sites are obviously reversed in TBI mice combined with hypothermia pre‐treatment (HT). But, the neuroprotective role of HT disappears in TBI mouse models under condition of blocking RBM3 expression with RBM3 shRNA. In other hand, overexpressing RBM3 by AAV‐RBM3 plasmid can mimic HT‐like neuroprotection against TBI‐induced chronic brain injuries, such as improving LTP and cognitive, loss of spines and tau hyperphosphorylation in TBI mouse models. Taken together, hypothermia pre‐treatment reverses TBI‐induced chronic AD‐like pathology and behaviour deficits in RBM3 expression dependent manner, RBM3 may be a potential target for neurodegeneration diseases including Alzheimer disease.     

INJURIES OF THE HAND AND FOREARM—Treatment of Damaged Soft Tissues

Successful primary repair of soft tissue injuries of the hand and forearm holds the ultimate disability to a minimum. The kinds of trauma and the resultant soft tissue damage may be classified. Attention to details and technique in carrying out the primary reparative operation on the injured hand largely obviates a crippling deformity or the need for much reconstruction later.     

Injuries of the hand and forearm; treatment of damaged soft tissues

Successful primary repair of soft tissue injuries of the hand and forearm holds the ultimate disability to a minimum. The kinds of trauma and the resultant soft tissue damage may be classified. Attention to details and technique in carrying out the primary reparative operation on the injured hand largely obviates a crippling deformity or the need for much reconstruction later.     

Soft-tissue injuries of the fingertip: methods of evaluation and treatment. An algorithmic approach

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Understand the anatomy of the fingertip. 2. Describe the methods of evaluating fingertip injuries. 3. Discuss reconstructive options for various tip injuries. SUMMARY: The fingertip is the most commonly injured part of the hand, and therefore fingertip injuries are among the most frequent injuries that plastic surgeons are asked to treat. Although microsurgical techniques have enabled replantation of even very distal tip amputations, it is relatively uncommon that a distal tip injury will be appropriate for replantation. In the event that replantation is not pursued, options for distal tip soft-tissue reconstruction must be considered. This review presents a straightforward method for evaluating fingertip injuries and provides an algorithm for fingertip reconstruction.

Human dental mesenchymal stem cells and neural regeneration

Nerve tissue presents inherent difficulties for its effective regeneration. Stem cell transplantation is considered an auspicious treatment for neuronal injuries. Recently, human dental mesenchymal stem cells (DMSCs) have received extensive attention in the field of regenerative medicine due to their accessibility and multipotency. Since their origin is within the neural crest, they can be differentiated into neural crest-derived cells including neuron and glia cells both in vitro and in vivo. DMSCs are also able to secrete a wide variety of neurotrophins and chemokines, which promote neuronal cells to survival and differentiation. Experimental evidence has shown that human DMSCs engraftment recovered neuronal tissue damage in animal models of central nervous system injuries. Human DMSCs can be a new hope for treatment of nervous system diseases and deficits such as spinal cord injury, stroke and Parkinson’s disease.
