Lafora disease with novel autopsy findings: a case report with endocrine involvement and literature review.

Pediatr Neurol 2014 Nov 7;51(5):713-6. Epub 2014 Aug 7.

Department of Medicine, Critical Care, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts.

Background: Lafora disease is a rare, autosomal recessive, progressive myoclonic epilepsy with onset typically in the second decade of life and uniformly fatal outcome. Most of the current literature focuses on diagnosis, genetic basis, neurological signs, and possible treatment of this currently incurable disease. On literature review of over 50 articles including over 300 patients, there were no comments on or pathologic description of endocrinologic issues in relation to Lafora disease.

Patient Description: We describe a patient with Lafora disease with severe neurological deterioration. During hospitalization for urosepsis, he exhibited thyrotoxicosis with a free thyroxine (T4) level greater than 7.77 ng/dL. On autopsy, he had lymphocytic thyroiditis and Lafora bodies throughout his organs including the anterior pituitary, hypothalamus, and pancreas.

Conclusions: This is the first report of the pathologic findings of Lafora bodies in endocrine organs. Although this patient's thyrotoxic state was likely not a direct result of his Lafora disease, given the diffuse deposition of Lafora bodies, endocrinologic abnormalities should be considered in patients with Lafora disease. Furthermore, acute decompensation in these individuals may arise not from a declining neurological status but from a coincidental disease process.

Pediatric cardiomyopathies: causes, epidemiology, clinical course, preventive strategies and therapies.

Future Cardiol 2013 Nov;9(6):817-48

Department of Pediatrics, University of Miami Miller School of Medicine, 1601 NW 12th Avenue, 9th Floor, Miami, FL 33136, USA.

Pediatric cardiomyopathies, which are rare but serious disorders of the muscles of the heart, affect at least one in every 100,000 children in the USA. Approximately 40% of children with symptomatic cardiomyopathy undergo heart transplantation or die from cardiac complications within 2 years. However, a significant number of children suffering from cardiomyopathy are surviving into adulthood, making it an important chronic illness for both pediatric and adult clinicians to understand. The natural history, risk factors, prevalence and incidence of this pediatric condition were not fully understood before the 1990s. Questions regarding optimal diagnostic, prognostic and treatment methods remain. Children require long-term follow-up into adulthood in order to identify the factors associated with best clinical practice including diagnostic approaches, as well as optimal treatment approaches. In this article, we comprehensively review current research on various presentations of this disease, along with current knowledge about their causes, treatments and clinical outcomes.

Closed-loop insulin therapy improves glycemic control in children aged <7 years: a randomized controlled trial.

Diabetes Care 2013 Feb 1;36(2):222-7. Epub 2012 Oct 1.

Division of Endocrinology, Boston Children’s Hospital, Boston, MA, USA.

Objective: To assess the possibility of improving nocturnal glycemic control as well as meal glycemic response using closed-loop therapy in children aged <7 years.

Research Design And Methods: This was a randomized controlled crossover trial comparing closed-loop with standard open-loop insulin pump therapy performed in an inpatient clinical research center. Ten subjects aged <7 years with type 1 diabetes for >6 months treated with insulin pump therapy were studied. Closed-loop therapy and standard open-loop therapy were compared from 10:00 p.m. to 12:00 p.m. on 2 consecutive days. The primary outcome was plasma glucose time in range (110-200 mg/dL) during the night (10:00 p.m.-8:00 a.m.). Secondary outcomes included peak postprandial glucose levels, incidence of hypoglycemia, degree of hyperglycemia, and prelunch glucose levels.

Results: A trend toward a higher mean nocturnal time within target range was noted for closed- versus open-loop therapy, although not reaching statistical significance (5.3 vs. 3.2 h, P = 0.12). There was no difference in peak postprandial glucose or number of episodes of hypoglycemia. There was significant improvement in time spent >300 mg/dL overnight with closed-loop therapy (0.18 vs. 1.3 h, P = 0.035) and the total area under the curve of glucose >200 mg/dL (P = 0.049). Closed-loop therapy returned prelunch blood glucose closer to target (189 vs. 273 mg/dL on open loop, P = 0.009).

Conclusions: Closed-loop insulin delivery decreases the severity of overnight hyperglycemia without increasing the incidence of hypoglycemia. The therapy is better able to reestablish target glucose levels in advance of a subsequent meal. Younger children with type 1 diabetes may reap significant benefits from closed-loop therapy.
