Derick Strange was an articulate and enthusi- astic teacher, an original thinker rather than a regurgitator of the views of others. His initiative resulted in the beginning of postgraduate teach- ing at the Kent and Canterbury Hospital and the eventual opening of the Kent Postgraduate Medical Centre. His most important contribution to the devel- opment of orthopedic surgery was probably the publication, in 1965, of his monograph entitled The Hip.

His name is eponymic with applied it to deformities wherever contracted spondylitic syndrome. To appreciate the importance of subcutaneous teno- tomy, the horrendous proportion and devastating effects of open surgery in pre-Listerian days must be kept in mind. As becomes obvious in this preface, the technic of Stromeyer’s procedure was used as a wedge for the development of muscu- loskeletal surgery vis-a-vis the brace and stretch- ing era of the early days of our specialty. His first paper on the subject was published in 1833; however, the classic of Stromeyer was his book on Operative Orthopedics. Even within his lifetime, the Syme amputation was recognized as a major technical advance. Hudson, The Mechanical Surgery, described the Syme amputation as follows: “No amputation of the inferior extremity can ever compare in its value to the subject with that of the ankle joint originated by Mr. That same year he resigned the chair James Syme was born in Edinburgh in November at the University of Edinburgh, to which he had 1799, the son of well-to-do parents.

In 1833 he was appointed to the chair of clinical surgery at the University of Edinburgh and was given an appointment on the staff of the Royal Infirmary. In 1853 Joseph Lister migrated from London to Edinburgh and established a warm relationship with James Syme. By his marriage with Agnus, Syme’s eldest daughter, Lister became the son-in- law of the distinguished professor and acted as his assistant and substitute on many occasions. Syme introduced conservative alternatives to major amputations and is best remembered for his contribution of ankle disarticulation with preser- vation of the heel pad as an alternative to below- knee amputation.

Junctional failure at a single synapse is an all-or-nothing process cheap 7.5mg meloxicam with visa arthritis in neck cause sore throat, but at the level of the motor neuron it is graded order meloxicam online pills arthritis in fingers relieve, as some muscle fibers may fail to contract while others respond normally purchase meloxicam 15mg with mastercard arthritis pain in elbow. The specifics of physiologic testing for neuromuscu- lar junction failure are complex and beyond the scope of this chapter, but excellent reviews exist. General features of enhancing the diagnosis of specific disorders of neuromuscular disorders in children are discussed below. SPECIFIC DISORDERS Autoimmune Myasthenia Gravis Autoimmune myasthenia gravis (MG) is by far the single most common disorder of the NMJ in children. This disorder is more common in adults, but can affect children as early as late infancy. In children, the general incidence correlates with age; MG is rarest in the youngest. It tends to affect orbital and bulbar-innervated muscles more than appendicular muscles, but there is wide individual variation. Muscle power may be normal after a period of rest, but with repeated activation available power drops quickly. The MG can manifest over a range from trivial to cata- strophic; the course can be stable and predictable or extraordinarily capricious. In general, the severity and course of any one individual with MG will declare itself relatively early in the course. For example, more than half of affected children have symptomatic weakness restricted to orbital muscles; if early eye muscle involvement does not spread more widely for 6 months it is unlikely to do so thereafter. Similarly, the tendency for minor intercurrent illness to trigger a sudden exacerbation that requires urgent medical intervention usually manifests within the first year. Therapy for Neuromuscular Junction Disorders 203 Diagnosis The diagnosis of MG is sometimes simple, sometimes extraordinarily difficult. Fortunately, however, the general difficulty of establishing a definitive diagnosis is inversely related to the need for that diagnosis. In those with severe illness the diag- nosis is usually straightforward, while the diagnosis in those with subtle transient symptoms may never be established with certainty. Clinical suspicion of MG should be increased whenever weakness is variable from time to time or with fatiguing effort. A frequent clinical test is to examine for decreasing range of extraocular mobility or ptosis with sustained up gaze. Another test is to look for early fatigue while sustaining a horizontal anteverted posture of the arms. In addition, four lines of evidence can contribute to the diagnosis: A positive test for antibodies against the acetylcholine receptor (anti-AChR antibodies) has the best predictive value of any single test. Unfortunately, anti-AChR antibodies are less often found in children than adults with MG, and much less often found in those with weakness restricted to the orbital muscles. In the practice of pediatrics, the antibody test thus often operates as does a ‘‘one way ratchet’’—useful if positive but not if negative. Electrodiagnostic testing, demonstrating a characteristic decremental response of muscle action potential amplitude—generally considered as anything greater than 10–15%—decreases from the first to the fourth or fifth response at 2–5 Hz stimulation, can be very useful, particularly if it can be shown to improve following rest or anticholinesterase treatment. Unfortunately this is an insensitive test, particularly in children and when weakness is transient. It is absolutely necessary to obtain a stable baseline and repeated testing, which are difficult to obtain in a less than fully cooperative child. When done poorly, false interpretation of testing to be abnormal is a risk. Sedating the child will improve the sensitivity of the test somewhat and substantially improve test specificity, but sedation of the child with enhanced potential for bulbar muscle weakness must be done in a controlled environment and carefully followed, increasing the morbidity and emotional and financial costs of the test. Very specialized electrodiag- nostic testing with a stimulated single fiber technique, looking for abnormal jitter and block, is occasionally useful. Evaluation of the clinical response to short-term anticholinesterase inhibi- tor medications can be very useful, but care must be taken to insure a qual- ity test. To be useful as a test for mysathenia, the child must manifest partial and easily testable weakness in a muscle at the time of treatment. A positive test is one where dramatic improvement can be demonstrated within seconds of infusion and the improvement then lapses back to baseline over a period of minutes. Because edriphonium clearly produces autonomic symptoms, care must be taken not to interpret as positive responses that could be attributable more simply to vigorous stimulation—such as the resolution of ptosis in a sleepy infant. In very subtle cases of transient symptoms—such as in children with vari- able ptosis, the sensitivity of each of the above methods may be limited. Use of a randomized paired on=off trial testing standard oral anticholines- terase medications with a blinded observer can be useful in some such cir- cumstances. One parent can give the medication, while the other is instructed to score whether or not the symptom of concern is improved. The observer should also be asked to iden- tify what were the most distinctive features—with post hoc reporting of observed anticholinergic features diminishing the power of the test. Treatment Treatment for children with confirmed MG should be tailored to clinical need. The range of required therapy is vast, with some requiring no therapy and some necessi- tating substantial intervention and tolerance for its associated morbidity (Table 1). Therapeutic modalities include short-term treatment of symptoms with acetylcholi- nesterase inhibiting agents, intermediate term treatment of the antibody response with plasmapheresis and IVIG, and long-term modifiers of the disorder with corti- costeroids, other immunosuppressives, and thymectomy. Oral acetylcholinesterase inhibitor therapy with pyridostigminine bromide can minimize weakness transiently. The onset of action is rapid, and duration of action is approximately 3–4 hr. Dosage can be increased slowly, titrating for benefit and the absence of side effects, usually abdominal cramping and diarrhea. Too high a dose may increase weakness, so the dose should not be increased too rapidly. Dosing is best at 4 hr intervals, with 3, 4, or 5 doses daily with meals to minimize GI side effects. An extended form is available for those who have symptoms in the morning before taking their dose. This come at only 180 mg doses, however, which is generally useful for the adult or child taking 60 mg or more with each dose. Use of the timespan form of pyridostigmine other than at night is contraindicated because of wide variation in daytime absorption and elimination pharmacokinetics. Intrave- nous neostigmine by continuous infusion can be substituted for oral mestinon in an ICU setting during crises, to tailor dosage and effect, and when oral medications cannot be tolerated.

Robert DANIS 1880–1962 Robert Danis was born in a small town in the Belgian province of Tournai. After classical studies at Anvers and Louvain, he studied medicine at the William DARRACH University of Brussels, from which he received his degree in 1904.

Darrach then returned from administration to his real abiding interest—surgery—and estab- lished the fracture service.

INTRODUCTION Defined by Gastaut in 1966, but first recognized in 1939 by Lennox, Lennox– Gastaut syndrome (LGS) has attracted considerable interest in the last half century. Responsible for less than 5% of childhood epilepsies, this catastrophic epilepsy con- sists of a typical triad of intractable seizures (tonic axial, atonic, myoclonic, and atypical absence), characteristic EEG abnormalities (bursts of slow spike and wave during the awake state and 10 Hz—fast rhythms with bursts of slow polyspikes during sleep state), and cognitive delay. Its disabling course and refractory nature give it an importance out of proportion to its incidence. DIAGNOSIS The diagnosis of LGS is clinical and rests on a constellation of clinical characteristics and electrographic findings. Characteristic Seizures Children with LGS have multiple seizure types, and their epilepsy is medically intractable with high frequency of seizures. The onset is in childhood, typically between 1 and 8 years with greatest frequency between 3 and 5 years. Seizures most commonly include tonic axial seizures, often nocturnal during non-REM sleep and associated with autonomic phenomena. Frequently described seizures include atonic and tonic seizures resulting in drop attacks, and prolonged atypical absence with automatisms sometimes accompanied by generalized seizures. Other seizure types may occur and predominate, such as in the myoclonic variant, or evolve, such as the increased frequency of generalized tonic–clonic convulsions in adolescence. Seizures usually occur multiple times a day, are usually brief but may be repetitive or prolonged. Tonic or 79 80 Vanderver and Gaillard atypical absence status may occur frequently in some patients. Frequent falls because of repeated seizures are disabling in many children with LGS and may result in injury. Characteristic EEG Findings Electroencephalographic tracings are not diagnostic, as in some epilepsy syndromes, but are characteristic of the diagnosis. The background is abnormal, with lower than age appropriate frequency of the posterior basic rhythm and intrusion of slow activ- ity generally. During wakefulness, generalized, bisynchronous slow spike-and-wave and polyspike-and-wave discharges (1–2. These may occur in bursts or as near continuous activity, and are most often irregular in frequency, distribution, and amplitude. This pattern may be asymmetric and intermixed with bursts of faster activity. Hyperventilation may increase the fre- quency of slow spike-and-wave discharges, but photic stimulation produces no par- oxysmal activation. During sleep, bursts of generalized fast spikes are seen at 10 Hz or more, maximal in non-REM sleep, and are the electrographic correlate of noctur- nal tonic seizures. They may obscure normal sleep architecture and, while not the pattern of electrographic status epilepticus of sleep (ESES), may occupy up to 50% of the recording. Generalized spikes, and in some patients multifocal spikes, can be seen throughout the recording. Neuropsychologic Disturbances Mental retardation is almost universal in LGS, with fewer than 10% of patients pre- serving near-normal intellectual functioning. Children may appear normal or near normal at onset with an abrupt deterioration following the onset of uncontrolled sei- zures, or may have a preceding encephalopathy, including infantile spasms. Overall, cognition progressively deteriorates, compounded by repeated trauma from falls and the effects of multiple anticonvulsants. Behavior problems abound and include autis- tic spectrum disorders, aggressiveness, and hyperactivity. EVALUATION—ETIOLOGY The differentiation of LGS from other catastrophic onset childhood epilepsies is important for prognosis and management. The seizure pattern may not appear char- acteristic initially and suggestive EEG patterns may not appear for several months. Therefore, it is not unreasonable to pursue diagnostic testing that may be suggested by the individual’s presentation—for example, that of progressive myoclonic epi- lepsy in a patient in whom the initial presentation includes myoclonic seizures. Very few patients with LGS, however, have documented abnormalities of metabolism. Concerns that LGS may be related to a developmental channelopathy or be an immune-mediated process have yet to be substantiated. In some series, 17–30% of patients with LGS have a history of infantile spasms. Therefore, central nervous system insults known to predispose to infantile spasms have been implicated in the pathogenesis of LGS. These include congenital infec- tions, sequela of neonatal hypoglycemia, hypoxic–ischemic encephalopathy, and traumatic brain injury. Lennox–Gastaut Syndrome 81 Structural abnormalities are the most common underlying etiology of sympto- matic LGS. Rarely, brain tumors have been known to cause LGS, although this raises the difficulty of differentiating true LGS from secondary bilateral synchrony. Tuberous sclerosis or other neurocutaneous syndromes are found in children with LGS, but not as frequently as in association with infantile spasms. Developmental brain malformations are the most common structural lesion to be reported in LGS, especially subcortical band heterotopia, bilateral perisylvian syndrome, and focal cortical malformations. It is therefore important to perform magnetic reso- nance imaging when considering the diagnosis of LGS, as there are reported cases of seizure reduction with focal surgical resection of lesions. Other types of neuroima- ging, including PET and SPECT scans, have not been uniformly helpful and are cur- rently better research than diagnostic tools. The majority of cases of LGS remain cryptogenic despite extensive metabolic evaluation and neuroimaging. Evaluation aimed at maximizing supportive care, such as neuropsychological assessment to identify baseline neurodevelopmental state and aid in appropriate educational placement are also important.
