Identification of sleep hypoventilation in young individuals with Becker muscular dystrophy: A pilot study.

AIM: To report on sleep hypercapnia in Becker muscular dystrophy (BMD) at earlier stages than ever recognized. SUBJECTS AND METHODS: This retrospective study examined nocturnal hypercapnia in six young Becker muscular dystrophy (BMD) patients with deletions of one or more exons of DMD gene. Clinical information, consecutive data on forced vital capacity (FVC%), forced expiratory volume in one second (FEV1%), peak expiratory flow (PEF%), peak cough flow (PCF), average PCO2 in all-night monitoring, and left ventricular ejection fraction (LVEF) were reviewed. RESULTS: In five BMD patients, including three who were still ambulant, nocturnal average PCO2 was elevated to >45 mmHg at 12-31 years of age. Noninvasive positive pressure ventilation was initiated in four patients. Gradual declines in FVC% and PEF% were evident in one BMD patient with exon 3-7 deletion, whereas these functions did not change in the remaining BMD patients. PCF, FEV1%, and LVEF were less informative for the assessment of respiratory function in this patient series. CONCLUSION: Sleep hypercapnia was present in certain BMD patients, which was unexpected from the routine pulmonary function tests. Individualized assessment of nocturnal PCO2, partly based on the deletion types, should be further explored in the clinical practice of BMD patients.

Effect of Intrathecal Baclofen on Delayed-Onset Paroxysmal Dystonia due to Compression Injury Resulting From Congenital and Progressive Spinal Bone Deformities in Chondrodysplasia Punctata.

BACKGROUND: Dystonia due to spinal lesions in adult patients is characterized by the provocation and/or amelioration of the spasm by somatosensory stimulation with a sensory trick. PATIENT DESCRIPTION: An infant with brachytelephalangic chondrodysplasia punctata developed flaccid tetraplegia due to cervical cord compression resulting from congenital atlantoaxial dislocation. Episodic, tonic extension of the extremities, neck, and trunk had appeared daily since age two years and was often provoked by tactile stimulation. Although decompression surgery was performed at age three years, progressive spinal deformity resulted in the aggravation of episodic dystonia thereafter, lasting for hours. Foot dorsiflexion and wearing a truncal brace for scoliosis inhibited these spasms. Intrathecal baclofen bolus injection transiently ameliorated the paroxysmal dystonia and detrusor-sphincter dyssynergia in the lower urinary tract. CONCLUSION: Paroxysmal dystonia is unusual in children with spinal cord lesions; however, it should be recognized for appropriate individualized clinical management.

[Care continuity for patients with eating disorder during transition from childhood to adulthood].

Eating disorder is mainly seen at the younger woman. In recent years, there has been a growing population of younger or elder women. In children, most of the eating disorder is anorexia nervosa(AN), but if eating disorders are prolonged, these switched over to ANBP and bulimia nervosa(BN). When a psychological problem becomes bigger that abnormal eating behavior and psychiatric disorder stand out at ANBP and BN, we can't answer as the pediatrics, and it's taken over psychiatry and the department of psychosomatic medicine. Because ego and the women's establishment and the lifestyle are related to eating disorder, long-term follow-up is needed. It's necessary to understand the feature of the eating disorder and adjust the treatment environment (including introduction to a medical specialist) early.
