X-linked mental retardation and characteristic physical features in two brothers with duplication Xp22-Xpter.

Two brothers are reported who share mental retardation, conjunctival teleangectasias (mainly equatorial) and characteristic flat face with small mouth and thin prolabia. At the neuropsychological examination, the older brother at 14 years showed a full scale IQ of 40 (WISC), with verbal IQ 45 and performance IQ 44. The younger brother at 7 years showed a full scale IQ of 58 (WPPSI), with verbal IQ 67 and performance IQ 55. Chromosome studies showed a duplication Xp22-Xpter in both brothers and in the inactivated X of their mother. The anomaly was not present in a 3rd healthy brother and in other healthy relatives. The mother has normal intelligence and did not present any of the physical features of her affected sons.

Clinical and EEG findings in eleven patients affected by mitochondrial encephalomyopathy with MERRF-MELAS overlap.

A study of mitochondrial DNA disease was carried out on 12 members belonging to three generations of a family from northern Sardinia. On the basis of the diagnostic criteria currently used in the classification of mitochondrial diseases a typical MERRF-MELAS overlap phenotype was seen in 11 patients with the mtDNA tRNA(lys) mutation at nucleotide position 8356. Clinical and instrumental investigations (EEG in particular) were made. Patients were divided into two groups: severely and mildly affected cases. The follow-up was reported. The aim of this study was to identify, through EEG, the early signs of the disease. The EEG findings recorded during the clinical evolution allowed us to recognize four degrees of cerebral involvement, and could also suggest the prognosis.

UK physicians' attitudes and practices in long-term non-invasive ventilation of Duchenne Muscular Dystrophy.

Previous studies have shown that long-term non-invasive ventilation (NIV) is not always routinely offered by all physicians in Duchenne Muscular Dystrophy (DMD), despite evidence that this treatment improves quality of life and survival. This study examined UK physicians' practices related to respiratory follow-up and DMD ventilation. A mailed questionnaire was used. Thirty-eight of the 59 (64%) UK physicians identified via the Muscular Dystrophy Campaign (MDC) responded. Eighty-one per cent of respondents felt ethically obliged to discuss NIV with families while 13% believed that NIV results in poor quality of life. Forty-seven per cent of physicians discuss in-depth the use of NIV when the patient is in respiratory failure. Eighty-four ventilated DMD patients in the respondents' practice use NIV (via Bi-Pap Nasal mask). Nearly 66% of physicians do not consider the public cost to be an impediment to offering NIV, despite significant problems with resources' allocation in their area. While the majority of UK physicians have comparable attitudes and practices regarding NIV, the questionnaire highlighted that not all specialists were aware of the existence of consensus guidelines regarding respiratory monitoring. In addition, different practices of disclosure of life-prolonging ventilation options were used by different physicians. Seventy-one per cent of physicians wished for national consensus guidelines for different DMD age groups.
