Review Case ReportsEarly diagnosis of pediatric Wernicke's encephalopathy.
Wernicke's encephalopathy may be fatal if untreated. Because Wernicke's encephalopathy is suspected to be underdiagnosed in children, the authors wished to assess the frequency of overlooked diagnosis and to establish pertinent findings that could lead to early identification of pediatric Wernicke's encephalopathy. The authors performed multiple literature searches seeking pediatric patients with Wernicke's encephalopathy (age = 20 years or younger). ⋯ Only six presented with the Wernicke's encephalopathy clinical triad (mental status changes, ocular signs, and ataxia) at neurologic onset; nine eventually demonstrated this triad. The high rate of patients diagnosed only at postmortem examination (41.9%) confirms that Wernicke's encephalopathy is underdiagnosed in children. Thiamine therapy is warranted if any component of the Wernicke's encephalopathy triad is present in an appropriate clinical setting.

ReviewMidazolam and pentobarbital for refractory status epilepticus.
Status epilepticus, a serious, life-threatening emergency characterized by prolonged seizure activity, occurs most commonly in pediatric patients. Although initial therapies with agents such as diazepam, phenytoin, or phenobarbital generally terminate seizure activity within 30-60 minutes, patients with refractory status epilepticus (RSE) lasting longer require additional intervention. ⋯ Both drugs effectively terminated refractory seizure activity, although pentobarbital use was complicated by hypotension, delayed recovery, pneumonia, and other adverse effects. Midazolam use was effective and well tolerated, affirming its value in pediatric RSE management.

Comparative StudyPrevalence of peripheral neuropathy with insulin-dependent diabetes mellitus.
Insulin-dependent diabetes mellitus (IDDM) is rare in Chinese children. There have been no reports on the prevalence of peripheral neuropathy in Chinese children with IDDM. This study aimed to determine prevalence of subclinical peripheral neuropathy in Chinese children with IDDM. ⋯ Thus, two children had symptomatic neuropathy and most (n = 24) had asymptomatic peripheral neuropathy. Two children had systemic hypertension, and one (3.8%) had laboratory evidence of early renal complications. Analysis of demographic and laboratory risk factors for the development of subclinical peripheral neuropathy revealed that the age of onset, duration of diabetes, level of hemoglobin A1c, triglyceride, cholesterol, serum creatinine, and urea, microalbumin/creatinine ratio, and urinary microalbumin excretion rate were significantly related to the development of subclinical peripheral neuropathy in specific nerves.

This study describes the clinical spectrum of patients with Klinefelter's syndrome and seizures. Klinefelter's syndrome is a sex chromosomal abnormality and the most common cause of male hypogonadism. It is characterized by cognitive dysfunction, hypogonadism, and abnormalities of physical maturation. ⋯ The seizures of six of 11 patients with epilepsy were well controlled with antiepileptic drugs. One patient had a single seizure and was not treated with medication. In patients with Klinefelter's syndrome and recurrent seizures, the electroclinical spectrum is heterogenous and outcome with antiepileptic drug treatment is favorable.

Case ReportsRespiratory failure in myasthenia gravis and negative pressure support.
A young female whose pyridostigmine treatment had recently been changed presented with myasthenia gravis, acute respiratory failure, and respiratory infection. She was supported with a noninvasive negative pressure cuirass device as an aid to optimizing medical therapies without the confounding factor of pharmacology-induced sedation and analgesia.
