Experiences With Aggressive Cardiac Rehabilitation in Pediatric Patients Receiving Mechanical Circulatory Supports.

Although some patients with fulminant myocarditis can be rescued owing to the improvements in mechanical circulatory support therapy, there are few reports providing evidence of cardiac rehabilitation during mechanical circulatory supports, particularly among pediatric patients. We treated two pediatric patients who underwent aggressive cardiac rehabilitation during mechanical support. Five days after the initiation of extracorporeal membrane oxygenation therapy aggressive cardiac rehabilitation was started in a 10-year-old girl with fulminant myocarditis. After explantation of the device, she was discharged on postoperative day 23. A 6-year-old girl with fulminant myocarditis started receiving cardiac rehabilitation two days after the initiation of an extracorporeal left ventricular assist device, despite having hemiplegia due to a recent broad stroke. She achieved an exercise capacity of supported walking for 280 meters after 127 days of cardiac rehabilitation and then went abroad to undergo heart transplantation when she was in the best physical condition possible. Early initiation of cardiac rehabilitation may be safe and effective for successful pediatric mechanical circulatory support therapy; this acts as a bridge to explantation or heart transplantation.

Reversible Motor Paralysis and Early Cardiac Rehabilitation in Patients With Advanced Heart Failure Receiving Left Ventricular Assist Device Therapy.

Advanced heart failure (HF) is sometimes complicated with brain impairment because of a microthrombosis caused by decreased left ventricular contraction or reduced brain circulation. Some patients may recover after left ventricular assist device (LVAD) implantation. However, little is known about the perioperative therapeutic strategy in patients suffering from such complications, particularly from a cardiac rehabilitation viewpoint. We report on a 58-year-old male patient with a previous history of poliomyelitis and a light paralysis in the left upper extremity, who suffered left hemiplegia with no evidence of stroke after hemodynamic deterioration. The combination therapy of perioperative cardiac rehabilitation and LVAD therapy improved his left hemiplegia as well as activities of daily living, and the patient was discharged on foot on postoperative day 72 after briefing the family on LVAD home management. Early initiation of cardiac rehabilitation before LVAD implantation may be a key for the smooth discharge and resocialization of patients suffering from brain impairment complicated with advanced HF.

An open trial of long-term testosterone suppression in spinal and bulbar muscular atrophy.

INTRODUCTION: We investigated the long-term effects of leuprorelin on leg-muscle strength in spinal and bulbar muscular atrophy (SBMA). We hypothesized that testosterone suppression by leuprorelin would prevent the progression of muscle weakness. METHODS: In a prospective, long duration, open trial, 16 SBMA patients underwent medical castration with leuprorelin for 3.5 years. Chlormadinone was coadministered initially to prevent a testosterone surge. The strength of knee extension and flexion were quantitated using a torque machine. RESULTS: Our hypothesis was rejected. The leg strength measures decreased significantly with the mean reduction of 22.3-27.8%. In a post hoc analysis, the leg strength of 4 patients with higher pretreatment baseline total testosterone levels and short disease duration of 1-6 years were stronger at baseline and decreased by only 12.3-15.7% after treatment. CONCLUSIONS: Leuprorelin was not effective in this small long-term treatment trial in SBMA. The possibility that earlier treatment might be beneficial may deserve further study.

Successful ambulation by surgical conversion in a complex form of epigastric heteropagus.

A female neonate with a complex form of epigastric heteropagus and with three legs was referred to us. The left leg appeared normal, the central one was hypoplastic and resected 1 month after birth, and the right one projected in the cranial direction with knee flexion contracture. Three bones of the parasite were sandwiched between the right ilium and the ischiopubic bones of the autosite. At the age of 4, we performed the subtrochanteric femoral osteotomy with 90 degrees of varization and rotation, along with knee disarticulation. Ambulation was successfully achieved with the prosthesis with a multiaxis knee unit.
