Progressive Myoclonic Epilepsy 99 Lafora body disease is clinically different from Unverricht–Lundborg disease because of the rapidly progressive neurological decline in Lafora body disease 100mg vibramycin with mastercard. The genetic defect has been identified in both and they are clearly different diseases. NEURONAL CEROID LIPOFUSCINOSIS (NCL) Neuronal ceroid lipofuscinosis (NCL) is an autosomal recessive disorder with onset at multiple ages and with varied initial symptoms. Depending on the age of onset, NCL is known as Santavuori–Haltia disease (infantile onset, 0–2 years), Jansky– Bielschowsky disease (late infantile onset, 2–4 years), Batten’s disease or Spielmeyer–Vogt–Sjogren disease (juvenile onset, 4–10 years) or Kuf’s disease (adulthood). Severe tonic–clonic or myoclonic seizures, developmental delay, and visual impairment are the presenting symptoms in the infantile and late infantile var- iants. A movement disorder, psychiatric or behavioral symptoms or visual loss may be the initial symptoms in older patients (juvenile onset and adults). The rate of pro- gression of disease is more fulminant with younger presentations. Nonetheless the disease is relentlessly progressive and ultimately fatal. Diagnostic studies supportive of the diagnosis are the electroretinogram, which may be abnormal early, and visual evoked potentials, which initially may be ‘‘giant’’ then disappear. Typical intracellu- lar fingerprint, curvilinear, or granular inclusions may be seen in multiple tissues, including skin, conjunctiva, muscle, leukocytes, or rectal mucosa. Although the underlying genetic defect has not been identified, genetic markers have been identi- fied for at least 10 subtypes with defects on chromosome 16 (juvenile) or chromo- some 13 (late infantile). SIALIDOSIS (CHERRY-RED SPOT MYOCLONUS SYNDROME) Two variants of Sialidosis are known.

At undergraduate level, medical schools strive to give students as much clinical exposure as possible; they are also increasingly giving students contact with patients earlier in the course. For postgraduates, “on the job” clinical teaching is the core of their professional development. How can a clinical teacher optimise the teaching and learning opportunities that arise in daily practice? Strengths, problems, and challenges Learning in the clinical environment has many strengths. Learners are motivated by its relevance and through active participation. Professional thinking, behaviour, and attitudes are “modelled” by teachers. It is the only setting in which the skills of history taking, physical examination, clinical Clinical teaching in general practice reasoning, decision making, empathy, and professionalism can be taught and learnt as an integrated whole. Despite these potential strengths, clinical teaching has been much criticised for its variability, lack of intellectual challenge, and haphazard nature. In other words, clinical teaching is an educationally sound approach, all too frequently undermined by problems of Common problems with clinical teaching implementation. Far from compromising spontaneity, planning provides structure and context for both teacher and students, as well as a framework for reflection and evaluation. Preparation is recognised by students as evidence of a good clinical teacher.

For most of the hereditary neuropathies vibramycin 100 mg fast delivery, the basic mechanisms are poorly understood and progression is irreversible. Even in the absence of a treatment for the primary pathology, however, there are many ways in which function can be enhanced and symptoms minimized. If the etiology of the neuropathy is identified, then therapy directed to the underlying illness may be beneficial to the neuropathy. Regardless of whether the etiology of the neuropathy is known or unknown, it may be possible to improve nerve function with therapy directed to improving nerve metabolism itself. If it is impossible to reverse the neuropathy, it still maybe possible to be helpful with symptomatic therapy. The following chapter discusses these general aspects of diagnosis and therapy. Those treatments directed to the underlying cause of specific disorders are listed in Tables 1 and 2. DIAGNOSIS Peripheral neuropathies are those conditions in which the pathological process pri- marily affects the peripheral nerves between the brainstem or spinal cord at one 177 178 Ouvrier et al. Table 1 Treatment of Inflammatory Neuropathies in Childhood Disorder Neuropathy Therapy Guillain–Barre´ Demyelinating IVIG l g=kg daily for 2 days syndrome or IVIG 0. If response is poor, consider immunosuppression with azathioprine, methotrexate, or cyclosporine A end and the peripheral terminus at sensory receptors or neuromuscular junctions at the other. In some cases the pathology also extends into the neuronal cell body in the spinal cord, dorsal root ganglion, or sympathetic chain. The major clinical hallmarks of the peripheral neuropathies are weakness, diminished tendon reflexes, and sensory loss. Recognition of one of several characteristic patterns of distribution (Table 3) is a useful first step in diagnosis. GENERAL MANAGEMENT Acute Polyneuropathies (Guillain–Barre´ Syndrome and Others) Meticulous supportive care is the mainstay of therapy in the acute polyneuropathies, such as the Guillain–Barre´ syndrome and those associated with a toxic or metabolic cause. Children with rapidly progressive weakness or sensory loss should be closely monitored in the hospital, ideally in an intensive care setting, until their clinical state stabilizes. This is particularly important in younger children in whom objective assessment of respiratory function is difficult.
