Civilian spinal cord injuries due to terror explosions.

STUDY DESIGN: Retrospective analysis of civilians with spinal cord injuries (SCIs) due to terror explosions. OBJECTIVES: To analyze and describe the clinical characteristics and rehabilitation outcomes of civilians with SCI due to explosions admitted for in-patient rehabilitation from 2000-2004. SETTING: SCI rehabilitation service, Tel Hashomer, Israel. METHODS: Retrospective chart review. Civilians with SCI due to terror-related gunshot wounds (GSWs) served as a control group. RESULTS: Eleven civilians with SCI caused by penetrating atypical foreign objects (PAFOs) and eight with GSWs were identified. The male-to-female ratio was approximately 2:1. Foreign objects were present within the spinal canal in seven patients, causing bone injury without canal penetration in three, and one patient had both bone injury and canal penetration. The most common level of injury was thoracic. Seven had complete motor SCI. Three individuals improved in American Spinal Injury Association status: one individual improved from B to C (cervical); one from C to D (thoracic); and the third from D to E (lumbar). Despite the similar acute hospital length of stay and functional independence measure (FIM) scores on admission, the PAFO group had a shorter rehabilitation length of stay with higher FIM scores and higher FIM efficiency at discharge. CONCLUSIONS: Although the pathophysiology of PAFO blast injuries is similar to the high-velocity GSWs or the high-energy military munition injuries, better rehabilitation outcomes were seen, with slightly higher FIM efficiency and efficacy at discharge. This result is likely to be caused by less neurological tissue damage at impact.

[From the "teeth-drawer", the "quick-pistol drawer" to the "stent"--the contribution of dentists to history].

In this short review, some facts on the historical background of dentistry are given along with descriptions of dentists who contributed to history in various fields. The history of general anesthesia is also tightly connected with a few dentists.

[The rehabilitation of patients with intellectual disability who sustained traumatic injury].

Mentally retarded people usually receive care in special social, vocational, behavioral or educational facilities. Only recently, we gained some experience in the rehabilitation after trauma of those with mental retardation. We presume that with the increasing awareness of the benefits of comprehensive and early rehabilitation after trauma, orthopedic surgeons, neurosurgeons, and physicians who work in intensive care units, refer more patients who had never before gained from this specialty. We would like to share our experience of the unique rehabilitation process of this population.

[Medical rehabilitation of patients with osteogenesis imperfecta (OI) and additional newly acquired disabilities].

Adults with Osteogenesis Imperfecta (OI) are rarely referred to facilities of general rehabilitation medicine. Recently, two OI patients were admitted to our department because of additional neurological disabilities: stroke and spinal cord injury. In these circumstances, the hospitalization course has different characteristics.

PTSD among Israeli former prisoners of war and soldiers with combat stress reaction: a longitudinal study.

OBJECTIVE: The aim of this study was to assess the long-term impact of war captivity and combat stress reaction on rates of posttraumatic stress disorder (PTSD) in Israeli veterans of the 1973 Yom Kippur war. METHOD: One hundred sixty-four former prisoners of war (POWs), 112 veterans who had had combat stress reaction, and 184 combat veteran comparison subjects filled out the PTSD Inventory, a self-report scale based on the DSM-III-R criteria for PTSD. The inventory diagnoses past and present PTSD, assesses its intensity, and provides a symptom profile. RESULTS: Thirty-seven percent of the veterans who had had combat stress reaction, 23% of the former POWs, and 14% of the comparison subjects had had diagnosable PTSD at some time in the past. The current rates were 13%, 13%, and 3%, respectively. The results showed different recovery rates over time: almost two-thirds of the veterans with combat stress reaction who had had PTSD in the past recovered, while less than one-half of the POW group showed this improvement. CONCLUSIONS: These findings indicate that small but significant proportions of the POWs and veterans with combat stress reaction were still suffering from PTSD almost two decades after the war. The different recovery rates in the two groups may reflect the differences in duration and severity of stressors, the impact of immediate intervention on long-term adjustment, or both.

Characterization of chronic pain and somatosensory function in spinal cord injury subjects.

The pathophysiology of the chronic pain following spinal cord injury (SCI) is unclear. In order to study it's underlying mechanism we characterized the neurological profile of SCI subjects with (SCIP) and without (SCINP) chronic pain. Characterization comprised of thermal threshold testing for warmth, cold and heat pain and tactile sensibility testing of touch, graphesthesia and identification of speed of movement of touch stimuli on the skin. In addition, spontaneously painful areas were mapped in SCIP and evoked pathological pain--allodynia, hyperpathia and wind-up pain evaluated for both groups. Both SCIP and SCINP showed similar reductions in both thermal and tactile sensations. In both groups thermal sensations were significantly more impaired than tactile sensations. Chronic pain was present only in skin areas below the lesion with impaired or absent temperature and heat-pain sensibilities. Conversely, all the thermally impaired skin areas in SCIP were painful while painfree areas in the same subjects were normal. In contrast, chronic pain could be found in skin areas without any impairment in tactile sensibilities. Allodynia could only be elicited in SCIP and a significantly higher incidence of pathologically evoked pain (i.e. hyperpathia and wind-up pain) was seen in the chronic pain areas compared to SCINP. We conclude that damage to the spinothalamic tract (STT) is a necessary condition for the occurrence of chronic pain following SCI. However, STT lesion is not a sufficient condition since it could also be found in SCINP. The abnormal evoked pain seen in SCIP is probably due to neuronal hyperexcitability in these subjects. The fact that apparently identical sensory impairments manifest as chronic pain and hyperexcitability in one subject but not in another implies that either genetic predisposition or subtle differences in the nature of spinal injury determine the emergence of chronic pain following SCI.

Acute pain threshold in subjects with chronic pain following spinal cord injury.

Studies of pain perception in patients with chronic pain have yielded contradictory results. While several studies found that acute pain threshold is raised in chronic pain subjects, others showed that these subjects exhibit a decreased pain threshold compared to pain free subjects. The aim of this study was to further examine this topic by studying pain perception in subjects with chronic pain following partial or complete spinal cord injury (SCI). We found a significant elevation of heat-pain threshold (measured above the level of lesion) in complete SCI subjects with chronic pain (CSCIP) as opposed to complete SCI subjects without pain, incomplete SCI subjects with (ISCIP) and without chronic pain and normal controls. This elevation of pain threshold was completely reversed following a complete relief of the chronic pain by DREZ lesion. Moreover, the CSCIP exhibited significantly higher scores in the McGill pain questionnaire compared to ISCIP, indicative of a more intense chronic pain perceived by these subjects. In addition, the chronic pain below the level of spinal lesion, reported by CSCIP originated from a significantly larger body area than that of ISCIP. These results indicate that a critical level of chronic pain must be perceived in order to induce an elevation in acute pain threshold.

Clinically insignificant (natural) autoantibodies against acetyl cholinesterase in the sera of patients with a variety of neurologic, muscular and autoimmune diseases.

Acetyl cholinesterase (AChE) antibodies were shown to be associated with myasthenia-like neuromuscular disease. However, it is not clear whether they cause the disease, or their presence is secondary to the disease or an unrelated epiphenomenon. Therefore, AChE antibodies were studied in the sera of 135 patients with neurologic, muscular and autoimmune diseases, using enzyme linked immunosorbent assay (ELISA), immunoblotting and enzyme inhibition assay. In 12 sera the AChE binding by ELISA was greater than 2 standard deviations (SDs) above the mean value of the 20 healthy controls. However, this increased binding was not disease-specific, had no clinical correlates and could not be demonstrated using Western blotting and AChE enzyme inhibition assay, suggesting that these antibodies are naturally occurring, pathogenically unimportant autoantibodies. The finding also supports a possible pathogenic role for the previously reported, high titer, high affinity, inhibitory AChE antibodies in the neuromuscular disease.

Posttraumatic residues of captivity: a follow-up of Israeli ex-prisoners of war.

BACKGROUND: This article examines the long-term impact of wartime captivity. METHOD: One hundred sixty-four prisoners of war (POWs) and 189 matched combatants of the 1973 Yom Kippur War filled out a series of questionnaires that assessed posttraumatic stress disorder (PTSD), general psychiatric symptomatology, and social functioning according to DSM-III-R criteria. RESULTS: Almost 2 decades after the war, ex-POWs exhibited higher rates and greater intensity of posttraumatic stress reactions, more general psychiatric symptomatology, and more severe problems in functioning at home, at work, and in the military than did the control group (Israeli veterans who were not POWs). They were also more likely to obtain official disability recognition and to seek psychological help. Their recovery was slower and professional help less effective. In addition, the veterans with PTSD in both groups had high rates of comorbid general psychiatric symptomatology. CONCLUSION: These findings point to the depth, range, and persistence of the stress residuals of wartime captivity.

Postsurgical prevertebral abscess of the cervical spine.

OBJECTIVES: Prevertebral abscess formation is an uncommon occurrence following cervical spine fusion surgery. Abscesses may present early or in a delayed fashion and require surgical drainage and long-term antibiotic treatment. The issues of osteomyelitis and the need for plate removal remain unresolved. STUDY DESIGN: A case series of six tetraplegic patients admitted for rehabilitation to the Chaim Sheba Medical Center (Tel Hashomer, Israel) is presented. METHODS: Five patients were trauma patients; one patient underwent repeated procedures and irradiation for tumor of the cervical spine. All patients developed prevertebral abscesses after a mean period of 30 days from their fusion surgery. Computed tomography scan was used in all patients to establish the diagnosis and define the extent of the infective process. All patients underwent one or more drainage procedures. The plate was removed in two patients at 1 and 4 months. RESULTS: Infection completely resolved in four patient and was refractory in one patient with malignant tumor, and a chronic small fistula remained in one case. Staphylococcus aureus was the main infective organism, but mixed infections were the rule. Even for a protracted course of infection, no significant osteomyelitis was encountered. CONCLUSIONS: Abscess formation after instrumentation of the neck may be more common than formerly recognized. Despite the prolonged course of disease and treatment, osteomyelitis is not a major concern. There is no automatic indication for plate removal to control infection, although plating may be safely removed after 10 to 12 weeks if the neck is explored and the cervical spine is stable. A high index of suspicion is warranted, and early recognition and diagnosis, prompt surgical drainage under general anesthesia, and long-term antibiotic treatment are key for eradication of the infective process. Prophylactic antibiotics may be of value. Meticulous antisepsis and surgical technique should be maintained to reduce the incidence of these severe complications.

Transverse myelitis in patients with antiphospholipid antibodies--the importance of early diagnosis and treatment.

Transverse myelitis (TM) is a rare manifestation of systemic lupus erythematosus (SLE) and the antiphospholipid syndrome (APS). No uniform therapeutic protocol exists for its treatment, and the prognosis is usually poor. Here we describe four patients having TM associated with antiphospholipid antibodies. Treatment measures and delay in diagnosis between symptom onset and the initiation of treatment varied between patients, but the earlier the diagnosis and the more aggressive the treatment the better was the patient's outcome. Based on these cases and on a literature review we suggest that early aggressive treatment (usually with pulses of methylprednisolone and cyclophosphamide) might improve the prognosis of patients with TM associated with antiphospholipid antibodies.

Disappearance of quadriparesis due to a huge cervicothoracic aneurysmal bone cyst.

A young man who had suffered from rheumatoid arthritis developed a huge cervicothoracic aneurysmal bone cyst and progressive quadriparesis. Complete recovery occurred after "incomplete therapy," which consisted of an open biopsy and a small dose of irradiation. This tumor was observed and characterized as a blood-filled cyst excavated from the bone. Because of the controversy in the literature over the benefit of surgery vs. irradiation, this report emphasizes the fact that even "partial" treatment may beneficially affect this tumor.

The 'hyperprosexia phenomenon' in traumatic brain injured patients (a forgotten term for an old problem).

In traumatic brain injured patients the basic functions of the cognitive, behavioral, emotional and intellectual systems are disturbed. The patients' ability to regulate the interaction between the ego and the external world is diminished and they present inflexible, concrete and sometimes inappropriate behavior. We have not observed anosognostic phenomena in these patients. Most of them are preoccupied with their physical impairments and unaware of their intellectual deficits. We hypothesize that this preoccupation or 'hyperprosexia phenomenon' may be observed in traumatic brain injured patients. The various neuropsychological, medical and philological aspects of these terms are discussed.

Are chronic spinal cord injured patients (SCIP) prone to premature aging?

Our hypothesis, based upon clinical observation and on the literature, is that chronic spinal cord injured patients are prone to premature aging. Physical and mental disabilities and prolonged immobilization change the entire homeostatic mechanisms into a new state. Thus, we feel that this lead to accelerated aging among these chronic handicapped persons.

Is the polio virus responsible for late central nervous system tumors?

A hypothesis is advanced concerning the relationship of poliomyelitis viruses and late developing neoplasia in the central nervous system. The literature is surveyed, and several experimental approaches based upon known evidence of viral and neoplastic behaviour are advanced. The present status of world polio incidence is discussed as it applies to this possible relationship.

Acute transverse myelitis, a possible vascular etiology.

Seven acute transverse myelitis patients are presented, in whom the course of illness suggests a vascular pathogenesis. In the absence of predisposing risk factors for vascular accidents and such systemic symptoms as occur frequently in vasculitic syndromes, association in hypothesized with isolated angiitis of the central nervous system. Combined treatment with corticosteroids and cyclophosphamide is, therefore, suggested for severe cases of acute transverse myelitis, in whom no etiology can be found.
