Project description:Isaac syndrome (IS) is a peripheral nerve hyperexcitability state associated with voltage-gated potassium channel (VGKC) complex antibodies. Major manifestations are muscle twitching, stiffness, hypertrophy, and dysautonomic features such as hyperhidrosis [Ahmed and Simmons. Muscle Nerve. 2015;52(1):5-12]. Neuropathic pain is a rare manifestation. We describe a case of IS characterized by muscle twitching and intractable neuropathic pain. Diagnostic workup included elevated VGKC complex antibodies and EMG/NC that showed neuromyotonic discharges. Neuropathic pain was initially difficult to relieve even after using multiple medications, including opiates, benzodiazepines, anticonvulsants, and intravenous immunoglobulin (IVIg). Moderate pain control was eventually achieved with long-term use of carbamazepine and subcutaneous immunoglobulin (SCIg). Common manifestations of IS are muscle twitching, stiffness hypertrophy, and dysautonomia [Ahmed and Simmons. Muscle Nerve. 2015;52(1):5-12]. Sensory manifestations such as neuropathic pain are rare, but, as illustrated by our patient, can be the most distressing symptom. In our patient, not only was neuropathic pain disabling but it also showed the least response to IVIg. The use of 200 mg of long-acting carbamazepine twice daily with weekly SCIg demonstrated the best response. This case highlights an uncommon but potentially resistant symptom of IS.

Interrelationships between Atopic Disorders in Children: A Meta-Analysis Based on ISAAC Questionnaires.

Project description:To study the prevalence and interrelationship between asthma, allergic rhinitis and eczema using data obtained from ISAAC questionnaires.The Medline, Pubmed Publisher, EMBASE, Google Scholar and the Cochrane Controlled Clinical Trials Register databases were systematically reviewed to evaluate epidemiological data of children with atopic disorders. To study these interrelationships, a new approach was used. Risk ratios were calculated, describing the risk of having two different atopic disorders when the child is known with one disorder.Included were 31 studies, covering a large number of surveyed children (n=1,430,329) in 102 countries. The calculated worldwide prevalence for asthma, eczema and allergic rhinitis is 12.00% (95% CI: 11.99-12.00), 7.88% (95% CI: 7.88-7.89) and 12.66% (95% CI: 12.65-12.67), respectively. The observed prevalence [1.17% (95% CI: 1.17-1.17)] of having all three diseases is 9.8 times higher than could be expected by chance. For children with asthma the calculated risk ratio of having the other two disorders is 5.41 (95% CI: 4.76-6.16), for children with eczema 4.24 (95% CI: 3.75-4.79), and for children with allergic rhinitis 6.20 (95% CI: 5.30-7.27). No studied confounders had a significant influence on these risk ratios.Only a minority of children suffers from all three atopic disorders, however this co-occurrence is significantly higher than could be expected by chance and supports a close relationship of these disorders in children. The data of this meta-analysis supports the hypothesis that there could be a fourth distinct group of children with all three disorders. Researchers and clinicians might need to consider these children as a separate group with distinct characteristics regarding severity, causes, treatment or prognosis.
