1/77. The prevention of irreversible lung changes following reversible phrenic nerve paralysis.

    phrenic nerve paralysis frequently follows operations on the neck such as resection of a cervical or first rib. It all too often passes unrecognised or is incorrectly treated, leading to permanent lung damage which may be severe enough as to result in a functional pneumonectomy. This is particularly unfortunate since the phrenic nerve paralysis is usually temporary. Three case histories are described of reversible paralysis of the phrenic nerve in which, due to prompt diagnosis, the ensuing lung changes were either prevented or immediatley treated. Intermittent assisted respiration with a Monaghan respirator was used to provide nebulised inhalations of mesna several times a day. The method is applicable via a tracheostomy, an endotracheal tube or a simple mouthpiece. The latter is illustrated. The therapy is not hindered by immobilisation of the head and neck and the level of consciousness of the patients is of no importance. Many chest x-rays demonstrate the rapid clearing of the lungs achieved. All three patients were discharged with perfectly normal lungs.

2/77. Real-time continuous visual biofeedback in the treatment of speech breathing disorders following childhood traumatic brain injury: report of one case.

    The efficacy of traditional and physiological biofeedback methods for modifying abnormal speech breathing patterns was investigated in a child with persistent dysarthria following severe traumatic brain injury (TBI). An A-B-A-B single-subject experimental research design was utilized to provide the subject with two exclusive periods of therapy for speech breathing, based on traditional therapy techniques and physiological biofeedback methods, respectively. Traditional therapy techniques included establishing optimal posture for speech breathing, explanation of the movement of the respiratory muscles, and a hierarchy of non-speech and speech tasks focusing on establishing an appropriate level of sub-glottal air pressure, and improving the subject's control of inhalation and exhalation. The biofeedback phase of therapy utilized variable inductance plethysmography (or Respitrace) to provide real-time, continuous visual biofeedback of ribcage circumference during breathing. As in traditional therapy, a hierarchy of non-speech and speech tasks were devised to improve the subject's control of his respiratory pattern. Throughout the project, the subject's respiratory support for speech was assessed both instrumentally and perceptually. Instrumental assessment included kinematic and spirometric measures, and perceptual assessment included the Frenchay dysarthria Assessment, Assessment of Intelligibility of Dysarthric speech, and analysis of a speech sample. The results of the study demonstrated that real-time continuous visual biofeedback techniques for modifying speech breathing patterns were not only effective, but superior to the traditional therapy techniques for modifying abnormal speech breathing patterns in a child with persistent dysarthria following severe TBI. These results show that physiological biofeedback techniques are potentially useful clinical tools for the remediation of speech breathing impairment in the paediatric dysarthric population.

3/77. Apneustic breathing in children with brainstem damage due to hypoxic-ischemic encephalopathy.

    To confirm the presence of apneusis in patients with hypoxic-ischemic encephalopathy and to clarify which factors influence their respiratory patterns, polygraphic studies were performed on two patients. Apneusis was clinically suspected in both patients who had severe brainstem damage. In one subject, inputs of vagal afferents from the gastrointestinal tract and the urinary bladder often resulted in extreme tachypnea instead of apneusis. lung inflation facilitated expiration during inspiratory arrest. Expiration preceded a periodic inhibition of rigospastic discharge in the right biceps muscle. In the other subject, prolonged inspiratory pauses with cyanosis occurred with or without preceding epileptic seizure. Both phenytoin dose reduction and treatment with tandospirone, a serotonin-1A agonist, were effective in improving the respiratory distress in this subject.

4/77. Trepopnea due to recurrent lung cancer.

    Trepopnea is a condition whereby breathing may be comfortable in one position but difficult or labored in another. A unique case with trepopnea due to recurrent lung cancer with right main pulmonary artery stenosis and left main bronchus obstruction is presented. The patient had developed trepopnea 3 months earlier, but developed orthopnea shortly before he was admitted to our hospital. An emergent wall stent implantation was performed via the right femoral vein in the sitting position with the patient's leg stretched out. The symptoms and respiratory function improved after stent implantation.

5/77. pyridoxine-dependent seizures responding to extremely low-dose pyridoxine.

    We report on a male infant with pyridoxine dependency and seizures from birth, controlled with pharmacological doses of pyridoxine at 4 months of age. seizures stopped between 30 and 80 days of age when very-low doses of pyridoxine were given in a multivitamin supplement. Daily dose was 0.5 mg that corresponded to 0.08 to 0.16 mg/kg/day when weight gain is considered. In previous reports doses have ranged from 0.2 to 30 mg/kg/day. Another distinctive feature was that this infant went into a coma and developed hypotonia and irregular breathing when pyridoxine was given by enteral tube which has usually been reported when the vitamin is given intravenously. Use of low doses of pyridoxine in multivitamin supplements could be a confounding factor for early diagnosis and appropriate treatment of pyridoxine-dependent seizures.

6/77. subcutaneous emphysema associated with chest tube drainage.

    BACKGROUND: subcutaneous emphysema may complicate a pneumothorax, but may also occur as a consequence of its treatment by chest tube drainage. The aim of this study was to evaluate the factors involved in the association between subcutaneous emphysema and chest tube drainage, and the clinical outcomes in these cases. METHODOLOGY: One hundred and sixty-seven patients undergoing chest tube drainage within a 12-month period were evaluated retrospectively. There were 30 reported cases of subcutaneous emphysema (SE). Comparisons were made between those with subcutaneous emphysema and those who did not develop this complication. RESULTS: A total of 134 patient notes were evaluated (25 SE and 109 non-SE). subcutaneous emphysema was more commonly associated with trauma, bronchopleural fistulae, large and bilateral pneumothoraces, and mechanical ventilation. subcutaneous emphysema was also associated with prolonged drainage, poor tube placement, tube blockage, side-port migration, and a greater number of chest tubes. Importantly, those with SE had a longer length of stay and increased mortality. CONCLUSION: subcutaneous emphysema can be spontaneous or traumatic, but is associated with avoidable causes such as inadequate chest tube drainage, particularly due to poor tube placement, anchorage and blockage, and also with side-port migration into the subcutaneous tissue. It is associated with an increased morbidity and mortality, and may indicate the need for urgent chest tube replacement.

7/77. A case of effective gastrostomy for severe abdominal distention due to breathing dysfunction of Rett's syndrome: a treatment of autonomic disorder.

    We report a case of 13-year-old-girl with Rett's syndrome and effectiveness of gastrostomy for severe paradoxical respiration, seizures and abdominal distention. Since the age of 3, she was observed to have typical hand-washing movement and autistic behavior. At the age of 8, she began to have hyperventilation and seizures in awake stage. Her symptoms were worse from year to year. At the age of 13, gastrostomy was done to treat severe abdominal distention. Her symptoms were improve dramatically by the gastric air removal through gastrobutton.

8/77. Disordered respiration as a levodopa-induced dyskinesia in Parkinson's disease.

    Symptomatic respiratory disturbance as a consequence of levodopa (L-dopa) therapy for Parkinson's disease (PD) has been described only rarely and may be underrecognized in clinical practice. We report on two patients with PD in whom the introduction or augmentation of L-dopa therapy was associated with the development of irregular and rapid breathing. Analysis of breathing patterns before and after L-dopa demonstrated a striking change in respiratory rate after administration of L-dopa, with the emergence of irregular tachypnea alternating with brief periods of apnea, in a pattern consistent with a central origin. In both cases, the temporal relationship of the respiratory disturbance to the administration of L-dopa suggested a peak-dose drug effect. Previous reports of L-dopa-induced respiratory dyskinesia are reviewed, and the potential mechanisms whereby L-dopa might influence the central control of respiration to produce irregular breathing patterns are discussed.

9/77. Reversible posterior leukoencephalopathy syndrome and silent cerebral infarcts are associated with severe acute chest syndrome in children with sickle cell disease.

    patients with severe acute chest syndrome (ACS) requiring endotracheal intubation and erythrocytopheresis are at increased risk for neurologic morbidity. This study examines patients with sickle cell disease who developed severe episodes of ACS, leading to endotracheal intubation, ventilatory support for respiratory failure, and erythrocytapheresis. magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) studies, a neurologic examination by a pediatric neurologist, and cognitive testing were done in all patients. Five consecutive patients, aged 3 to 9 years, were identified with severe ACS. All patients developed neurologic complications resulting from ACS episodes, including seizures (n = 2), silent cerebral infarcts (n = 3), cerebral hemorrhage (n = 2), and reversible posterior leukoencephalopathy syndrome (n = 3). Children with severe ACS should have a magnetic resonance image of the brain, neurologic examination by a neurologist, and cognitive testing to detect the presence of neurologic morbidity.

10/77. A new extra-vertebral treatment model for incomplete spinal cord injuries.

    Advances made in recent times in spinal cord injury repair research will soon take us toward a cure in paraplegics. But what are the prospects for quadriplegics? Certain fundamental issues make treatment approaches to quadriplegia different and difficult. Injury at cervical region poses additional problems for any surgical intervention with life-threatening risks of i) endangering respiratory function, ii) cavitation, cysts, and syringomyelia formation extending cephalad to the injury, and iii) mid-lower cervical injuries, lower motor neuron death, and the resultant degeneration of brachial plexus axons would still leave the upper limbs denervated and paralyzed even as treatment procedures might successfully salvage the lower limbs. With these apparently insurmountable impediments in quadriplegic cord repair, it would be wise to turn to alternative treatment strategies. Conventional treatment models since the days of Ralph Gerard (1940) have all used intra-vertebral procedures. We present here a plausible extra-vertebral repair model suitable for incomplete cord injuries at cervical, thoracic, and lumbar levels. The procedure consists of identifying the extent of viable grey-white matter in the injured area and to utilize it efficiently as a "neural tissue bridge." Next, labile state is induced by using botulinum toxin/colchicine (Krishnan, 1983, 1991; Krishnan et al., 2001 a,b) and Ca channel blockers in the motorsensory nerve terminals of polisegmentally innervated skeletal muscles that "bridge" the injured cord segments. This would retrogradely induce a redundant state of intra-spinal growth of nerve terminals and new synaptic connections within those viable neural tissues, as well as promote effective relinking of the injured cord ends and enhance motor-sensory recovery.
