During a six-year period, an adolescent girl developed a polyglandular disease characterized by hypoparathyroidism, chemical diabetes, growth failure and pubertal delay, hypercholesterolemia, and hypomagnesemia. A slowly progressive neurological disorder occurred simultaneously, consisting of progressive external ophthalmoplegia, mitochondrial myopathy, ataxia, neural deafness, mental subnormality, atypical retinitis, corneal dystrophy, cataract, and increased protein level in the cerebrospinal fluid. An intracardiac conduction defect was also found. This disorder, the cause of which is uncertain, is termed oculocraniosomatic disease. Our patient is apparently unique in that there was an associated hypoparathyroidism.

Report of a case of chronic progressive external ophthalmoplegia combined with retinitis pigmentosa, optic atrophy, marked attenuation of the retinal vessels, maculopathy, and complicated cataract. Visual fields and acuity were severely impaired. The ophthalmoplegia was histologically identified as ocular myopathy. In a review of 181 cases with CPEO the disease was found to be associated with retinitis pigmentosa in 7 per cent and with atypical pigmentary retinopathy in 36 per cent of the cases. A distinction of these two types of retinal dystrophy is justified by the clinical features and may indicate different hereditary patterns.

We studied a large family with a dominantly inherited mitochondrial myopathy characterized by progressive external ophthalmoplegia, dysphagia, cataract, lactic acidosis, exercise intolerance, and early death. Morphologic studies of muscle biopsies suggested mitochondrial heteroplasmy and revealed ragged-red fibers and decreased histochemical reactions for cytochrome c oxidase and succinate dehydrogenase. Biochemistry showed a partial defect of cytochrome c oxidase and a mild generalized reduction of other mitochondrial enzymes requiring mitochondrial DNA-encoded subunits. Southern blot analysis and PCR amplification showed mitochondrial DNA deletions in muscle of all affected members, but not in lymphocytes or fibroblasts, suggesting a tissue-specific distribution. Deletions were multiple and seemed to increase with time and to correlate with the severity of the disease.

We examined ophthalmologically nine children with lactic acidosis. All showed abnormal ocular findings. Optic atrophy was present in six patients, nystagmus in three, blepharoptosis in one, cataract in one, and limitation on abduction in one. We believe that optic atrophy is the most frequent ocular finding and that nystagmus and ophthalmoplegia are common associations in patients with childhood lactic acidosis.

The overall prevalences of microvascular complications and their association with dietary, clinical, and metabolic characteristics have been studied in 503 Mexican type II diabetic subjects. Average daily dietary intakes were 1866 kcal, 46.5% as carbohydrate, 13.7 mmol cholesterol, 8.7 g fiber, and a polyunsaturated/saturated fat ratio of 0.98. Prevalence rates of microvascular and metabolic complications were as follows: background retinopathy 12.3%, exudative retinopathy 24.2%, proliferative retinopathy 8.1% (1% blind, 4% able to read large print only), 9.1% of patients had cataract, 15.9% nephropathy, and 40.8% peripheral neuropathy. In addition, 3.6% had experienced transient lower motor neuron facial paralysis and 0.2% oculomotor paralysis. Patients with retinopathy had a longer mean duration of diabetes, were less obese at the time of examination, and had higher initial and mean blood pressures and higher mean fasting blood glucose levels when compared with those without retinopathy. Similar differences were observed between groups with and without nephropathy except that mean blood glucose levels were similar in the two groups. The presence of peripheral neuropathy was associated with longer duration of diabetes, less obesity, higher mean blood pressure and mean blood glucose levels, and lower hemoglobin concentration. Patients treated with diet alone had significantly lower prevalences of all three microvascular complications but they also had significantly shorter duration of diabetes and lower mean blood glucose levels. However, multivariate analyses on the subgroup of 360 patients who had repeated fasting blood glucose measurements for at least 5 yr demonstrated associations between retinopathy and duration of diabetes, mean blood pressure and mean blood glucose, and percent calories from carbohydrate.(ABSTRACT TRUNCATED AT 250 WORDS)

A 62-year-old female had severe progressive ophthalmoplegia associated with facial, pharyngeal and limb muscle involvement. When 40, she had undergone surgery for bilateral cataract present for about 20 years. Biopsies of skeletal muscles indicated myopathy; histochemistry and electron microscopy gave evidence of abnormal mitochondria in type I fibres. Bilateral cataract needing surgical treatment at 32 was the prominent symptom in her daughter, then with only mild facial weakness. Despite absence of ophthalmoplegia, similar pathological changes were observed in an inferior oblique muscle. The child of the former, a 10-year-old clinically healthy boy, had been surgically treated for a bilateral cataract at the age of 3. As indicated by a review of literature, cataract is not an exceptional occurrence in this particular type of ocular myopathy and therefore should be included within its multisystem associations. The same HLA haplotype (A2-B21) was found in the three patients.

A 67-year-old woman experienced a severe headache and vomiting. A computed tomographic (CT) scan showed a mild subarachnoid hemorrhage. Cerebral angiography revealed a saccular aneurysm at the apex of the basilar artery. Several days later, she noticed mild hemiparesis of the left extremities. She underwent a clipping operation on the aneurysm by approaching from the right temporal love. Postoperatively, she developed diplopia and dilatation of the left pupil. Cerebral angiography revealed an occlusion of the left posterior cerebral artery. She was admitted to another hospital in order to continue rehabilitation. General physical examination was normal. Neurological examination revealed paralysis of the left medial and left inferior rectus muscles and palsy of the left inferior oblique muscle. The pupil of the left eye was dilated, measuring 5 mm in diameter, and it did not constrict to any stimuli. The left superior rectus and levator palpebrae superioris functioned normally. Visual acuity and visual fields were normal except for the influence of a senile cataract. She had a mild left hemiparesis, slight left ataxia and slurred speech. She had numbness of the left half of the body. A CT scan showed small low density areas in the right thalamus and left cerebellar hemisphere. Her ophthalmologic findings were compatible with the inferior branch palsy of the oculomotor nerve. The ophthalmoplegia of this case seems to be due to partial damage of the oculomotor nerve induced by ischemia of vascular supply. It is supposed to be caused by a vasospasm of the left posterior cerebral artery following a clipping operation of the basilar apex aneurysm.

A large Swedish family with members affected by progressive external ophthalmoplegia with hypogonadism were followed-up and reviewed. Hypogonadism included delayed sexual maturation, primary amenorrhea, early menopause, and testicular atrophy. Cataracts, cerebellar ataxia, neuropathy, hypoacusia, pes cavus, tremor, parkinsonism, depression, and mental retardation were other features observed in this family. Muscle biopsy samples of advanced cases showed ragged-red fibers, focal cytochrome c oxidase deficiency, and multiple mtDNA deletions by Southern blot analysis. An autosomal dominant mode of inheritance was evident with anticipation in successive generations. Linkage analysis excluded the chromosome 10q23.3-q24.3 region reported as being linked to the disease in a Finnish family with autosomal dominant progressive external ophthalmoplegia. We report for the first time clinical evidence for anticipation in a family with autosomal dominant progressive external ophthalmoplegia. We hypothesize that the nuclear gene causing this enigmatic disorder may be directly influenced by an expansion of an unstable DNA sequence and that the resulting phenotype is caused by a concerted action with multiple deletions of mtDNA.

In a 33-year-old man, mitochondriopathy was diagnosed upon short stature, auditory impairment, gynaecomastia, hypogonadism, vertical ophthalmoplegia, cerebral atrophy, leucencephalopathy, cataract, hypertrabeculated left ventricle, hypothyroidism, diabetes mellitus, glomerulonephritis necessitating kidney transplantation, general wasting, polyneuropathy, abnormally high lactate levels on exercise, partially reduced cytochrome-c oxidase staining and abnormally structured mitochondria on muscle biopsy. Mitochondrial DNA (mtDNA) analysis revealed 1 novel (A15662G) and 3 known mtDNA transition(s) (T3398C, T4216C, G15812A) affecting the cytb and ND1 gene, respectively. Three of the patient's transitions were also detected in blood leukocytes of the patient's maternal grandmother, mother and brother. Mutant mtDNA was heteroplasmic at >75% in the patient's skeletal muscle.
