Activities and outcomes in an outpatient palliative care clinic (PCC) have attracted little attention in the literature. We describe the results of our patient appointment scheduling process, our efficacy in relieving cancer-associated symptoms and an analysis of risk factors for patient non-compliance with the appointment schedule. Over a one-year study period, 730 first-time appointments were scheduled and 73.1% of them were kept. Only patients who had kept 3 consecutive visits (n=203) were included in the symptom control analysis. All symptoms except constipation, physical weakness, and anxiety improved significantly with palliative care. History of alcohol abuse was not associated with poorer pain control. A low Karnofsky index and high anxiety levels were identified as risk factors for early withdrawal from the PCC scheduled appointment. These data indicate that the PCC is an effective place for symptom management, but specific organizational strategies are needed to encourage patients to comply with scheduled appointments.

Idiopathic inflammatory myositis is characterized by progressive weakness of the proximal muscles. There is a higher risk of malignancy than in the normal population. The aim of this study was to evaluate the frequency of malignancy among 251 myositis patients. We also compared clinical and immunological characteristics of cancer-associated myositis with primary myositis. There were no malignancies among polymyositis, overlap, or juvenile myositis patients. Twenty-two of ninety dermatomyositis patients also had a malignant disease. Patients with cancer-associated dermatomyositis were significantly older than primary myositis patients and had more severe cutaneous and muscle symptoms. Dysphagia and diaphragmatic involvement were more frequent among cancer-associated patients, while extramuscular features were less frequent. After successful treatment of the malignancy, we were able to manage myositis symptoms. One-year survival rate was significantly better in primary dermatomyositis patients. The subset of cancer-associated myositis differs from primary myositis in many aspects of its clinical and immunological features. Prognosis and life expectancy in cancer-associated myositis patients is determined by the underlying malignant disease. Therefore, age- and sex-specific examinations for detection of an underlying malignancy are important in the management of patients with dermatomyositis.

The recent development of a rat model of amyotrophic lateral sclerosis (ALS) in which the rats harbor a mutated human SOD1 (G93A) gene has greatly expanded the range of potential experiments, because the rats' large size permits biochemical analyses and therapeutic trials, such as the intrathecal injection of new drugs and stem cell transplantation. The precise nature of this disease model remains unclear. We described three disease phenotypes: the forelimb-, hindlimb-, and general-types. We also established a simple, non-invasive, and objective evaluation system using the body weight, inclined plane test, cage activity, automated motion analysis system (SCANET), and righting reflex. Moreover, we created a novel scale, the Motor score, which can be used with any phenotype and does not require special apparatuses. With these methods, we uniformly and quantitatively assessed the onset, progression, and disease duration, and clearly presented the variable clinical course of this model; disease progression after the onset was more aggressive in the forelimb-type than in the hindlimb-type. More importantly, the disease stages defined by our evaluation system correlated well with the loss of spinal motor neurons. In particular, the onset of muscle weakness coincided with the loss of approximately 50% of spinal motor neurons. This study should provide a valuable tool for future experiments to test potential ALS therapies.

Spinal cord injury (SCI) results in muscle weakness but the degree of impairment at the level of single fibers is not known. The purpose of this study was to examine the effects of T9-level SCI on single muscle fibers from the tibialis anterior of rats. Significant decreases in cross-sectional area (CSA), maximal force (Po), and specific force (SF = Po/CSA) were noted at 2 weeks. Atrophy and force-generating capacity were reversed at 4 weeks, but SF remained impaired. Maximum shortening velocity (Vo) did not change after injury. SCI thus appears to affect various contractile properties of single muscle fibers differently. Normal cage activity may partially restore function but new interventions are needed to restore muscle fiber quality.

Dermatomyositis is a rare inflammatory myopathy that has characteristic cutaneous lesions. Although many malignancies are associated with dermatomyositis, urogenital malignancies have rarely been reported to be associated with dermatomyositis. We report here on the first case of ureteral cancer associated with dermatomyositis. A 42-year-old man presented to us with a skin rash. A clinical diagnosis of dermatomyositis was made due to the skin lesions, muscle weakness, arthralgia, the increased erythrocyte sedimentation rate and the increased creatine kinase level. The patient revealed microscopic hematuria and abnormal urine cytology during the investigation for the underlying malignancy. Retrograde pyelography demonstrated a suspicious lesion in the right mid-ureter, and the ureteroscopic biopsy revealed the urothelial carcinoma. Although an operation was recommended, the patient died of pneumonia associated with his interstitial lung disease, which is one of the poor prognostic indicators of dermatomyositis.

Intraosseous schwannomas or neurilemomas are rare benign neoplasms that account for less than 0.2% of primary bone tumours. Very rarely they have been observed in lumbar vertebrae. We report a neurilemoma involving the lower thoracic spine and present the clinical, radiological and histological findings with surgical management and 5-year follow-up. An 18-year-old-male presented with back pain and deteriorating locomotor function. Neurological examination revealed wasting of both calves and weakness in plantar flexion and dorsiflexion bilaterally. X-rays showed a D12 vertebral body abnormality with cystic changes and collapse of the body and pedicle. MRI showed a tumor occupying the D12 vertebrae with perivertibral protrusion compressing the thecal sac. Surgical decompression, excision and stabilisation with an extendable cage, bone graft and anterior rod system were achieved through a thoracolumbar approach. Histology results confirmed an intraosseous schwannoma with no remnants of an originating nerve. These tumors are rare but can be successfully treated with surgical excision and maintenance of spinal stability with recovery of neurological and functional change. Recurrence is uncommon.

For investigating the changes in continuous biomechanical nature of bone bearing intensive stress in vivo, we adopted the animal model of persistent intensive stress. Thirty-seven rabbits were involved in the experiment; they were randomly divided into control group (5 rabbits) and trained group (32 rabbits). All animals were forced to jump and run about 300 times everyday in the electric stimulation cage so as to simulate the persistent intensive stress on tibias for different periods. Subsequently, all animals were sacrificed at different times (1-11 weeks), and all tibias of them were collected for biochemical investigation. By torsion destroy test, the experiment showed that the changes of biomechanical nature appeared obviously in a period of 6 weeks or so in the experiment. Furthermore, during the 2nd-3rd week of each period, the biomechanical indexes decreased strikingly; the abilities of deformation resistant dropped, the twisting rigidity decreased (69.7% lower than control, P< 0.01), the flexible index inereased (203.2% higher than control, P<0.05), the angle of twisting destroy increased (102.9% greater than control, P< 0.05). And the tibial mechanical strength declined too; the destroy torsion, energy absorption and energy absorb density decreased (most of them being 50% lower than control, even accounting for 34.5% of control; P< 0.05 or P< 0.01). We noticed that the biomechanical properties of bone endured persistent intensive stress presented periodicity and the period of change in bone biomechanical nature covered about 6 weeks in the experiment. Therefore, we have ground to conclude that a weakness period did exist when rabbit tibias endured 2-3 weeks persistent intensive stress, and such weakness did exist at the 2nd-3rd week of each training period.

Cough is an important component of airway clearance, particularly in individuals with intrinsic pulmonary disease, weakness of respiratory muscles, or central nervous system disease that impairs breathing. The use of assisted cough to enhance airway clearance in individuals with neuromuscular disease is essential to produce and maintain peak cough flow above a minimum and thereby avoid retained secretions that cause infection, inflammation, and respiratory failure. Periodic insufflation of the lung above a reduced vital capacity is also important, to maintain range of motion of the thoracic cage and avoid progressive respiratory disability. Mechanical insufflation-exsufflation is a therapy in which the device (the CoughAssist In-Exsufflator is the only currently marketed insufflation-exsufflation device) gradually inflates the lungs (insufflation), followed by an immediate and abrupt change to negative pressure, which produces a rapid exhalation (exsufflation), which simulates a cough and thus moves secretions cephalad. Mechanical insufflation-exsufflation is used with patients with neuromuscular disease and muscle weakness due to central nervous system injury. Insufflation-exsufflation decreases episodes of respiratory failure, particularly during upper-respiratory-tract infection, and provides greater success in weaning from mechanical ventilation than do conventional methods. Alternatives to insufflation-exsufflation that can produce sufficient peak cough flow for airway clearance include (1) insufflation to maximum insufflation capacity (via breath-stacking with a bag and mask, a volume ventilator, or glossopharyngeal breathing) followed by a spontaneous cough, and (2) manually assisted cough with an abdominal thrust. The effectiveness of insufflation-exsufflation in patients with obstructive lung disease, such as chronic obstructive pulmonary disease or asthma, and in pediatric patients, is less clear.

An adult female Moluccan cockatoo (Cacatua moluccensis) was evaluated for a 10-day history of progressive ataxia and weakness. The bird had been exposed intermittently over a 3-day period to a cage that had previously housed juvenile raccoons. Results of diagnostic tests were inconclusive and, despite supportive care, the bird died 7 days after the initial presentation. Histopathologic examination revealed a single nematode larva in the midbrain that was consistent with Baylisascaris species and multifocal granulomas in the left ventricle of the heart. The neurologic disease in this bird was attributed to encephalitis caused by neural larval migration of the raccoon roundworm, Baylisascaris procyonis.

SBMA is a hereditary neurodegenerative disease caused by expansion of a trinucleotide CAG repeat, which encodes the polyglutamine tract, in the first exon of the androgen receptor (AR) gene. The phenotypic difference with gender, which is a specific feature of SBMA, has been recapitulated in a transgenic mouse model of SBMA expressing the full-length human AR containing 97 CAGs under the control of a cytomegalovirus enhancer and a chicken beta-actin promoter (AR-97Q). Affected SBMA mice demonstrate small body size, short life span, progressive muscle atrophy and weakness as well as reduced cage activity, all of which are markedly pronounced and accelerated in the male SBMA mice, but either not observed or far less severe in the female SBMA mice. There is increasing evidence that testosterone, the ligand of AR, plays a pivotal role in the neurodegeneration in SBMA. The striking success of androgen deprivation therapy in SBMA mouse models has been translated into phase 2, and then phase 3, clinical trials. Moreover, animal studies have also been revealing key molecules in the pathogenesis of SBMA such as heat shock proteins, transcriptional co-activators, and axon motors, suggesting additional therapeutic targets.
