To our knowledge, the juvenile form of spongy degeneration of the CNS (SD-CNS); van Bogaert-Bertrand disease) has been described previously only three times. We report the case of 21 1/4-year-old Japanese woman who was first seen at the age of 11 with growth retardation, ptosis, and ophthalmoplegia. Her progressive neurodegenerative disease included retinitis pigmentosa, blindness, partial deafness, cerebellar dysfunction, hyporeflexia, and muscle wasting. Simultaneous endocrine defects were diabetes mellitus and probable hyperaldosteronism. Heart block developed later. She died of bronchopneumonia. Autopsy showed CNS stigmas typical of spongy degeneration. Additional findings included peripheral nerve demyelination, neurogenic muscle atrophy, pituitary and pancreatic atrophy, right adrenal agenesis, and a left adrenal coritcal lipid-cell adenoma. To our knowledge, our patient was the oldest survivor, the first patient of Japanese ancestry, and had a unique concurrence of certain oculoendocrine defects.

A 7-year-old boy presented with bilateral ptosis and atypical retinitis pigmentosa. Before age two, he had had an Fe-refractory anemia, with neutropenia and thrombopenia. Just prior to the ophthalmic examination, the patient developed lactate acidosis, muscular hypotonia, ataxia and increased protein in the spinal fluid. Pancytopenia, pancreas dysfunction and growth retardation are the main features of Pearson's syndrome, most children not surviving beyond age three. The cause of Pearson's syndrome in our patient turned out to be a 5 kb deletion in the mitochondrial DNA. Similar deletions have been described in the Kearns-Sayre syndrome. It seems that children who survive the initial phase of Pearson's syndrome, may develop Kearns-Sayre syndrome.

Two sisters in the first year of life presented with a proximal tubulopathy of unknown etiology. They subsequently developed a pluritissular disorder including diabetes mellitus, skin abnormalities, mitochondrial myopathy with ragged-red fibers, and cerebellar ataxia. Their mother had ptosis, ophthalmoplegia, and muscle weakness. Analysis of the mitochondrial respiratory chain showed a complex III deficiency in both skeletal muscle and lymphocytes of the second girl. Southern blot analysis provided evidence for a heteroplasmic partial duplication of the mtDNA (26 kb), involving one full-length and one partly deleted mitochondrial genome and with one single abnormal junction between the genes for ATPase 6 and cytochrome b. Using PCR amplification of lymphocyte DNA, we were able to detect minute amounts of duplicated molecules in the mother, which provided evidence for maternal inheritance of the partial duplication. While maternal transmission of point mutations have been reported in Leber disease, retinitis pigmentosa, and MERRF disease, this observation is, to our knowledge, the first example of a maternally inherited duplication of the mitochondrial genome in man.

Refsum's disease is a polyneuropathy due to a hereditary error in the metabolism of a fatty acid, phytanic acid, usually leading to cardiac failure only at an advanced stage of the disease. The authors report the case of two brothers with Refsum's disease revealed by a heart failure before the clinical stage of the peripheral neuropathy. In the younger brother, the affection started at the age of 22 years by an acute pulmonary oedema which revealed a dilated, hypokinetic myocardiopathy, associated with retinitis pigmentosa, ptosis, anosmia and biological myolysis. The normal plasma concentration of phytanic acid measured several times led to the conclusion of Kearns-Sayre syndrome even if certain aspects were atypical (moderate conduction disorders, no characteristic aspect in the muscle biopsy). Five years later, the older brother, aged 28, presents a dyspnea on effort which leads to the discovery of a hypokinetic, hypertrophic myocardiopathy, slightly dilated, associated with cardiac conduction disorders, retinitis pigmentosa, anosmia and biological myolysis. The plasma concentration of phytanic acid being very high. Refsum's disease was diagnosed and the diagnosis of younger brother was corrected. From the study of these two cases, the characteristics of the cardiac disorders can be specified: the cardiopathy can reveal the disease and correspond to a dilated or hypertrophic myocardiopathy. The diagnosis of the disease can be difficult because the plasma phytanic acid may remain at normal level, thus requiring the assay of the activity of phytanate oxydase. The existence of ophthalmologic signs (retinitis pigmentosa or progressive ophthalmoplegia externa) associated with a myocardiopathy must systematically lead to a search for Refsum's disease, this diagnosis having fundamental therapeutic implications (died, even plasmapheresis).(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence and mode of inheritance of major genetic eye diseases have been investigated in China since the establishment of the Section of Ophthalmic Genetics of the Chinese Society of Genetics. Mass screening of genetic eye diseases has been undertaken in many districts in China, covering more than 700,000 people, and more than 5000 pedigrees of genetic eye diseases have been collected and analysed all over China. Based on these data, the prevalence and mode of inheritance of dyschromatopsia, degenerative myopia, retinitis pigmentosa, congenital ptosis, congenital microphthalmos, congenital cataract, congenital glaucoma, Leber's optic atrophy, corneal dystrophy, congenital nystagmus, coloboma of the eye, congenital aniridia, retinoblastoma, macular dystrophy, simple myopia, primary glaucoma, and strabismus have been investigated, and the results are presented.

Leber's congenital amaurosis is a hereditary clinical disorder that may be associated with several different diseases. This study consists of a retrospective review of 43 cases. Twenty of our patients had fundus appearances that resembled retinitis pigmentosa. Five had normal-appearing fundi. The remainder had other, previously reported fundus abnormalities, with the exception of two patients who demonstrated a new fundus finding, a nummular pigmentary pattern. Other associated eye anomalies included cataracts, keratoconus, ptosis, and strabismus. The most frequent systemic associations were mental retardation, cystic renal disease, skeletal disorders, and hydrocephalus.

Weakness of the external eye muscles was believed to be of genetic origin in 94 of 97 patients studied and was familial in 73 patients. Thirty patients had congenital ptosis alone or with weakness of other ocular muscles. The lack of progression and high incidence of other congenital anomalies suggested that congenital ptosis had in most instances a development etiology. Neurogenic congenital ptosis was documented in one instance and was suspected in another patient. The most common causes of progressive ophthalmaplegia with onset after birth was myotonic dystrophy and ocular muscle dystrophy. On clinical and genetic grounds, ptosis associated with retinitis pigmentosa was considered as a distinct disease and there was no conclusive evidence that ocular muscle dystrophy and oculopharyneal dystrophy were separate diseases. The relatively high incidence of familial myasthenia gravis was probably due to the selection of the patients. Two pairs of sibs with "chondrodystrophic myotonia" were included in the study. Progressive external ophthalmoplegia with onset after birth was neurogenic in three instanced. It accompanied motor neuron disease, Kugelberg-Welander disease and an undertermined disease affecting the central and peripheral nervous system, each in one patient.

A 21 year old patient was operated for bilateral ptosis and external ophthalmoplegia at 13 years of age. At this time there were no signs of retinitis pigmentosa or atrioventricular block, features of the Kearns and Sayre Syndrome (1958) which were detected five years later. His bundle recording showed an intrahisian block (1 degree proximal and a complete distal block) with a trifascicular block, the latter persisting alone during a brief return to sinus rhythm. This is one of the rare cases of the Kearns and Sayre Syndrome with documented His bundle recordings and the only reported case with intrahisian block. The patient also suffered from bilateral neural deafness. The patient's condition remains stable after implantation of an isotopic cardiac pacemaker and he now leads a normal life. A review of 52 previously published cases shows that this rare condition appears to be caused by a mitochondrial abnormality, which, for an unknown reason, affects only the neuromuscular and cardiac conduction systems. The prognosis is poor when swallowing and respiration are affected, but this does not occur in all cases. As cardiac conduction abnormalities are the other life-threatening complication, cardiac pacing has greatly improved the prognosis of these patients.

In addition to ophthalmic symptoms (ptosis and retinitis pigmentosa), our patient displayed symptoms of disturbances of cardial conduction as well a mitochondrial myopathy. The latter was confirmed histologically. The order in which the symptoms of the disease appear may vary, but the close cooperation of ophthalmologist, neurologist and internist is vital in any event.
