The most devastating failure of the clinical assessment is to overlook the presence of a tumor bacteria reproduction process order vantin online, infection using topical antibiotics for acne buy discount vantin on-line, or a spinal compression syndrome virus website buy vantin without prescription. This can be avoided in most cases home antibiotics for acne order discount vantin online, if the examiner considers possible specific causes during history taking and physical examination. The importance of this triage has led to the suggestion of a so-called flag system (see Chapter 6). The red flags are of particular relevance because they help to detect serious spinal disorders [1]: features of cauda equina syndrome severe and worsening pain (especially at night or when lying down) significant trauma fever unexplained weight loss history of cancer patient over 50 years of age use of intravenous drugs or steroids Features of cauda equina syndrome include urinary retention, fecal incontinence, widespread neurological symptoms and signs in the lower limb, including gait abnormality, saddle area numbness and a lax anal sphincter [1]. A relevant paresis can be defined as the inability of the patient to move the extremity against gravity. It is particularly important to recognize a progressive weakness because emergency exploration and treatment is necessary. It is always astonishing that patients do not spontaneously report a disturbance of their bowel and bladder function because they do not suspect a correlation with a spinal problem. After red flags are explored, the clinical assessment focuses on the three major complaints which lead the patients to seek medical advice:) pain) functional impairment) spinal deformity Of these three complaints, pain is by far the most common aspect. The diagnosis of non-specific neck/back pain is made by exclusion History contributes most to a clinical diagnosis 204 Section Patient Assessment Pain Although pain is the most common complaint in patients with spinal disorders, our understanding of the pathophysiology of pain is still scarce. However, molecular biology has recently unraveled some basic mechanisms of pain generation and persistence which help to better understand patients presenting with spinal pain (Chapter 5 is strongly recommended for further reading). Differentiation of Pain the most obvious differentiation of spinal pain syndromes is based on the region of the pain, i. A differential diagnosis of the segmental and peripheral innervation [11] is obvious and mandatory. Referred pain usually originates from the back or neck but radiates into the extremities. However, knowledge of the so-called sclerotomes [7] is helpful in understanding otherwise unexplained musculoskeletal pain. In the case of a L5 radiculopathy, for example, patients most frequently experience pain in the greater trochanter region (L5 sclerotome). Axial pain is defined as a locally confined pain in the axis of the spine without radiation. Important triage questions) How much of your pain is in your arm(s)/hand(s) and how much in your neck Pain which is exclusively or predominantly in the arms/hands is indicative of a radicular syndrome (disc herniation, spondylotic radiculopathy or myelopathy). Pain which is exclusively or predominantly in the legs/feet indicates a radicular syndrome (disc herniation, foraminal stenosis) or spinal claudication. A differentiation of axial pain is less straightforward and it remains difficult to relate a specific pathomorphological alteration to this pain. Pain descriptors Sensory dimension) throbbing) shooting) stabbing) sharp) cramping) gnawing According to Melzack [21]) hot-burning) aching) heavy) tender) splitting Affective dimension) tiring-exhausting) sickening) fearful) punishing-cruel History and Physical Examination Chapter 8 205 Figure 1. Segmental innervation of the skin Pain can be further differentiated according to its character. Melzack [21] has developed a questionnaire which distinguishes sensory and affective pain descriptors (Table 2) which can be helpful in the assessment of the pain character. Peripheral innervation of the skin History and Physical Examination Chapter 8 207 Figure 3. Segmental innervation of the bones 208 Section Patient Assessment A classic differentiation of pain is often based on the temporal course, i. Chronic pain is not simply a prolonged acute pain but undergoes distinct alterations in the pain pathways. Pain intensity should routinely be assessed with regard to outcome assessment of a future treatment (see Chapter 40). However, acute excruciating pain should raise the suspicion of a neural compression or a severe instability. Myelopathic or radicular pain can sometimes be so severe that it is difficult to control it by analgesics. Pain Onset Slowly progressive pain worsening during the night is indicative of tumor/infection the onset of pain can be helpful in inferring the underlying pathology. It is reasonable to explore whether the pain onset followed a specific incident or not:) incident with immediate pain onset) incident with delayed pain onset) no incident, slowly progressive pain It is most obvious in patients who sustained an injury. Some elderly patients report a loud crack in their back as the onset of pain which is indicative of an acute osteoporotic fracture. Rear-end collision accidents typically result in a delayed pain onset (whiplash-associated disorders). More frequent and difficult to interpret is a situation in which the patient has sustained a minor incident. An acute onset of back pain which subsequently radiates into an extremity is indicative of a radiculopathy caused by a disc herniation. The vast majority of patients with spinal disorders do not report an incident but a slowly progressive pain and discomfort which initially is unrecognized. In the case of a slowly progressive pain which worsens during the night or rest, the examiner should suspect a tumor or infection. Pain Modulators Slowly progressive pain indicates degenerative disorders, but do not overlook tumor or infection the assessment of modulators of pain is helpful for the diagnosis of specific pain syndromes and can guide the examiner to the underlying pathology.

Metamizol (Dypirone) is an excellent alternative to acetaminophen at the same dose regimen provided the patient is not allergic to it and has no bone marrow disease popular antibiotics for sinus infection discount vantin online visa. On the contrary treatment for dogs fever generic 200mg vantin mastercard, the literature shows similar surgical outcomes with better pain control in patients who received ketorolac at less than 110 mg/day after spine procedures [22 antibiotic resistance education generic 100mg vantin visa, 51 antibiotic resistance livestock feed generic vantin 100mg on-line, 61]. Wound infiltration at the beginning and the end of the operation greatly reduces the amount of anesthetics and opioids required in the first few hours after surgery, allowing patients to be scheduled to go home the same day. Side effects are often prominent including gastrointestinal, excessive sedation, respiratory depression and poor incidental pain relief. However, the double epidural catheter technique provides better postoperative analgesia, earlier recovery of bowel function, fewer side effects, and higher patient satisfaction. Cervicothoracic epidural catheter Epidural catheter at the level of C7/T1 allows for excellent pain control in cases with posterior fusion and/or a transthoracic approach. Anesthesiologists with special expertise in spine surgery play an important role in the perioperative team in charge of patients. The anesthesiologist will lay out a plan to manage anesthesia in each case, but this plan must be closely integrated into the surgical plan. Therefore, the anesthesiologist must be involved before surgery to permit a team plan for the case, no matter how simple it may seem. Critical aspects of the intraoperative anesthesia care are airway management, positioning on the operative table, techniques to minimize surgical bleeding, pain control and organ perfusion. Techniques to control bleeding must be balanced against ocular complications and cord function and perfusion. Techniques to achieve proper pain control postsurgery must be balanced against effective bone fusion and clean healing. Patients with an unstable cervical spine require careful fiberoptic tube placement, avoiding drops in blood pressure that might further jeopardize the cord condition. Patients coming for transthoracic surgical approaches might require lung deflation by using a bronchial blocker or other device to facilitate surgical exposure. Antibiotic prophylaxis before starting the operation is mandatory in most spine surgery cases to preclude colonization of implants. In simple cases of day surgery procedures, the goals are rapid recovery of anesthesia without nausea, vomiting and pain. Local anesthesia infiltration before the surgery and at the end facilitates an anesthetic approach with minimal opioids. At the conclusion of the anesthesia and surgery, the issues are pain control and again airway management. Multimodal analgesia along with epidural catheters offers excellent results with low morbidity and high levels of patient (and surgeon) satisfaction. The decision to keep the patient intubated in the first few hours after C-spine or major spine operations should rely on the clinical assessment by the team regarding the physiologic and anatomic conditions of the individual patient.

Several studies have explored the natural history of progression in idiopathic scoliosis during adolescence antibiotics for sinus infection for adults discount vantin 100mg without prescription. Larger curves generally have a higher progression risk than smaller ones [25 antibiotics heartburn buy vantin 200mg without a prescription, 125 antimicrobial yoga pant cheap generic vantin canada, 220] and progression is more frequent in female patients [5 antibiotic resistance biofilm purchase vantin 100mg overnight delivery, 25, 56, 221, 222]. Early studies on the natural history of scoliosis included mixed types of scoliosis and reported higher mortality rates, more back pain and psychosocial adverse effects such as a lower rate in married women or a reduced ability to work [148, 156]. More recent selective studies on adolescent idiopathic scoliosis did not show such unsatisfactory outcomes. However, they found back pain to occur more frequently than in the normal population. This data suggests adolescent idiopathic scoliosis to be a rather benign spinal disorder especially in cases of small to moderate curve sizes. Conservative measures consist of:) physiotherapy) bracing) electrotherapy So far, there is no evidence for the efficacy of electrotherapy [117]. A recent review of the effectiveness of physiotherapy in the treatment of scoliosis has identified 11 studies [151]. Therefore, the literature fails to provide solid evidence that physical exercises influence the natural history. Nevertheless, physiotherapy is a helpful adjunct to reduce symptoms related to muscle imbalance and to improve or preserve back function [224, 225]. The limitations of physiotherapy with regard to curve progression have to be clearly communicated to the patient and their parents prior to treatment. Patients having physiotherapy remain under surveillance with regard to curve progression. Physiotherapy does not arrest curve progression Casts and Bracing Infantile and Juvenile Idiopathic Scoliosis In early onset (< 6 years), scoliosis therapy is dominated by the progression risk. Patients whose curves resolve should be followed until maturity to rule out any progression during the growth spurt [2]. In resolving curves plaster-bed treatment showed no advantage over physiotherapy with regard to the time of resolution or functional outcome after 25 years [48]. Then, fulltime bracing is started for at least 2 years and until there is no further progression to be observed [2]. Prognosis is good if total correction is achieved before the prepubertal growth spurt [138]. If no full correction may be achieved, progression may occur, possibly necessitating surgery. However, it must be borne in mind that the primary goal is to prevent curve progression through bracing. The treatment is considered successful if the initial curve size at treatment entry can be preserved at the end of bracing. Often an improvement occurs during therapy but is lost after brace cessation [31, 139, 227]. The possible psychological distress of a long-term therapy such as bracing and the efficacy of the treatment must carefully be considered [63, 135, 157, 165, 219]. The effectiveness of conservative treatment modalities has been the subject of several studies [117]. Other studies found no significant differences for bracing versus natural history [158]. A recent survey among members of the Scoliosis Research Society and of the Pediatric Orthopaedic Society of North America revealed a high degree of variability with regard to the opinion of the effectiveness of brace treatment [52]. Based on the current literature, there seems to exist only limited evidence for the effectiveness of bracing. Intensive counselling of the patients and their parents is necessary to explain the pros and cons of the intervention, risks and potential outcome. The indications for surgery for idiopathic scoliosis depend on:) risk for progression) skeletal maturity) curve type) curve magnitude) cosmetic appearance) failure of conservative treatment Surgery has to be well planned in advance and requires a dedicated team taking care of children and adolescents. Intraoperative neuromonitoring has become the standard of care to control spinal cord function during correcting surgery [67, 131, 168, 173] (see Chapters 12, 15).

Idiopathic Scoliosis Chapter 23 625 In patients with small curves, males and females are about equally affected, but with increasing curve magnitude the female-to-male ratio changes to the disadvantage of female adolescents [6, 22, 23, 97]. Between 3 and 6 years, the femaleto-male ratio is 1:1, between 3 and less than 10 years it is 2:1 to 4:1 [95] and at 10 years of age the ratio is about 8:1 [172]. However, some factors that seem to play a role in the etiology and pathogenesis of this spinal deformity have been detected. On the contrary, the circumferential growth of the vertebral bodies and pedicles by membranous ossification was found to be slower than in controls. Asymmetrical anterior column growth with posterior tethering may lead to scoliosis Genetic Factors Several studies have shown that idiopathic scoliosis develops within affected families with a higher incidence than in the general population [44, 233]. Studies with monozygous twins exhibited a concordance of almost three-quarters for the development of scoliosis whereas the concordance in heterozygous twins was found to be about one-third, which is still higher than in first-degree relatives [100]. Beside these observational approaches several attempts were made to statistically analyze a potential linkage of genes to the disorder. Complex segregation analyses indicate that there is a major gene controlling scoliosis [8]. However, such a gene has not been detected yet and the aforementioned studies with monozygous twins suggest that variable gene expression and environmental factors also influence the development of scoliosis. There is a genetic predisposition for idiopathic scoliosis Connective Tissue and Skeletal Muscle Abnormalities Scoliosis is linked to several connective tissue diseases such as Marfan syndrome. Therefore, alterations in the extracellular matrix of connective tissue were the subject of investigations on the etiology of scoliosis. Some authors found a different collagen composition of the nucleus in scoliosis patients [171] while others did not [164, 186]. Changes in the paraspinal musculature were also discussed as possible etiologic factors. Several studies found a muscle fiber distribution (slow-twitch and fast-twitch) between the convex and the concave side of the curve [27, 189, 199, 201, 235]. However, it can only be speculated whether these alterations are the result or the cause of the disease [129]. Connective tissue disorders appear to play a role in scoliosis 626 Section Spinal Deformities and Malformations Thrombocyte Abnormalities, Calmodulin and Melatonin the myosin/actin contractile systems of thrombocytes and skeletal muscle are quite similar. It was therefore suggested that if there is an abnormality in the contractile apparatus of the skeletal muscle leading to scoliosis, abnormalities should also be apparent in platelets. As thrombocytes are independent of the axial skeleton, changes must be independent of secondary effects caused by the deformity itself. Patients with larger idiopathic curves exhibited more metallophilic thrombocytes, whereas the reticular type was mainly found in the controls. This difference was thought to be due to different membrane permeability indicating a membrane defect. Calmodulin interacts with actin and myosin and regulates the calcium influx from the sarcoplasmatic reticulum. It therefore regulates the contractile properties of muscles and platelets and has also been investigated as a potential etiologic factor. Elevated calmodulin concentrations in thrombocytes were found to be associated with progressive adolescent scoliosis while the levels in patients with non-progressive curves and controls were similar [102]. Melatonin is decreased in patients with progressive curves whereas it is normal in stable curves [133]. As melatonin binds to calmodulin and acts as an antagonist to it, it may also play an important role in the regulation of the aforementioned platelet changes. In conclusion, these reports suggest a defect in the contractile system of platelets associated with scoliosis. The adult idiopathic scoliosis has to be differentiated from:) primary degenerative or "de novo" scoliosis (see Chapter 26) the adult idiopathic type is an idiopathic scoliosis which already existed at the end of growth and can exhibit progressive secondary degenerative changes [1]. The classification is based on six different curve patterns, three lumbar spine modifiers and a sagittal thoracic modifier. The curves in the scoliotic spine are differentiated into structural and non-structural curves. Two recent studies have investigated validity and reliability comparing the King and Lenke classifications [155, 182]. The Lenke classification considers all anatomical curve types and the sagittal thoracic profile Clinical Presentation History Patients presenting with idiopathic scoliosis before adulthood usually present without severe clinical signs and symptoms. Frequently, the scoliosis is accidentally discovered by family members, teachers, friends, school nurse or family physicians because of the back or shoulder asymmetry. Teenagers sometimes realize the scoliosis is present when they have problems finding perfectly fitting clothes (waistline asymmetry).
