Two brothers, aged 11 years 6 months and 2 years 3 months, with psychomotor and growth retardation, episodes of weakness, ataxia,
ophthalmoplegia
, and elevated levels of blood pyruvate were shown to have a deficiency in the pyruvate dehydrogenase complex (PDH). When they ate a diet high enough in fats to cause ketonemia but not acidosis, there was a fall in blood pyruvate levels, a decrease in the frequency and severity of the episodes of neurological deterioration, an increased rate of growth and development in the younger brother, and increased strength and endurance in the older one. The possibility of dietary treatment makes the early diagnosis of PDH deficiency more important. Determination of blood pyruvate and lactate levels following a standard
glucose
meal (
glucose
-pyruvate test) appears to be the most reliable screening test for this condition.

Leigh's disease is one of the mitochondrial encephalomyopathies. This article presents a 7-month-old baby boy who had been well-being since birth until 6 months of age when episodic downward gaze of both eyes with limitation of horizontal eye movement were noted. This episode of cranial nerve palsies lasted about 4-5 days and subsided spontaneously. The second attack was noted one month later, to be associated with hypotonia and truncal ataxia. Episodic hyperventilation with resultant gasping and myoclonus was noted at the third attack but spontaneous respiration resumed soon with persistent
ophthalmoplegia
and truncal ataxia. Lumbar puncture, brain MRI, amino acid assay and cardiac echo all showed negative finding. The oral
glucose
lactate stimulation test revealed an elevation of lactic acid, brain stem evoked potential indicated bilateral obscure 4th and 5th waves, and muscle biopsy showed ragged red fibres with aggregation of structurally abnormal mitochondria noted under electron microscope. Coenzyme Q, thiamine and carnitine had been given before biochemical study; however, the neurological symptoms did not show any improvement. Biochemical study finally revealed normal respiratory chain enzymes including NADH-coenzyme Q reductase, succinate coenzyme Q reductase and cytochrome c oxidase while other enzymes were technically unavailable for study. Unfortunately the patient died at 18-month-old due to respiratory failure.

In late 1987 there was an outbreak in Canada of gastrointestinal and neurologic symptoms after the consumption of mussels found to be contaminated with domoic acid, which is structurally related to the excitatory neurotransmitter glutamate. We studied the neurologic manifestations in 14 of the more severely affected patients and assessed the neuropathological findings in 4 others who died within four months of ingesting the mussels. In the acute phase of mussel-induced intoxication, the patients had headache, seizures, hemiparesis,
ophthalmoplegia
, and abnormalities of arousal ranging from agitation to coma. On neuropsychological testing several months later, 12 of the patients had severe anterograde-memory deficits, with relative preservation of other cognitive functions. Eleven patients had clinical and electromyographic evidence of pure motor or sensorimotor neuronopathy or axonopathy. Positron-emission tomography of four patients showed decreased
glucose
metabolism in the medial temporal lobes. Neuropathological studies in the four patients who died after mussel-induced intoxication demonstrated neuronal necrosis and loss, predominantly in the hippocampus and amygdala, in a pattern similar to that observed experimentally in animals after the administration of kainic acid, which is also structurally similar to glutamate and domoic acid. We conclude that intoxication with domoic acid causes a novel and distinct clinicopathologic syndrome characterized initially by widespread neurologic dysfunction and then by chronic residual memory deficits and motor neuronopathy or axonopathy.

Wernicke's encephalopathy should be considered as a possible diagnosis in comatose and hypothermic patients. The classic triad of confusion,
ophthalmoplegia
(or nystagmus) and ataxia may be absent, and the history of alcohol abuse or other causes of thiamine deficiency may be unknown. Left untreated, acute Wernicke's encephalopathy has a 17 percent mortality rate. Since the morbidity from Wernicke's encephalopathy is potentially reversible with parenteral thiamine, and large doses of thiamine can be given without documented ill effects, it is recommended that all comatose or hypothermic patients, as well as those with more classic presentations of Wernicke's encephalopathy, be given parenteral thiamine before administration of
glucose
.

Seven patients with histologically proven mitochondrial myopathy with
ophthalmoplegia
(OMM), 6 of them nondiabetic, 1 affected by diabetes mellitus (DM), were submitted to a study of
glucose
tolerance and of insulin receptors on peripheral mononuclear cells and cultured skin fibroblasts. The diabetic patient, who had the typical features of the Kearns-Sayre syndrome (KSS) and deleted muscle mitochondrial DNA (mtDNA) presented a low insulin secretion rate under physiological stimuli (intravenous
glucose
and glucagon) whereas the insulin receptor parameters were found normal. The other patients showed a normal
glucose
tolerance and normal insulin receptors. Our data support the hypothesis that insulin receptors are not involved in the pathogenesis of DM associated with mitochondrial encephalomyopathies, in contrast to other neuromuscular inherited disorders. The clinical and biological features of DM presented by our KSS patient show normal insulin receptor parameters in spite of a defective insulin secretion, possibly depending on mitochondrial dysfunction.

Many reports of diabetic
ophthalmoplegia
have been published from the clinical points of view. However, there have been only three autopsied cases in which the ocular nerves were investigated histopathologically. A 72-year-old housewife was diagnosed to have glycosuria at the age of 67, but no medical treatment was done. She admitted to the hospital, because of acute onset of right eyelid drooping and diplopia for previous four days. She showed complete eyelid ptosis, moderate dilatation of right pupil, loss of light reaction, and extraocular muscle palsy except abduction on the right. Blood pressure was normal. A
glucose
tolerance test was diabetic and HbA1c was moderately increased. Her diabetes was fairly well-controlled with a diet therapy and injection of lente insulin. Two and a half months after admission, the course of illness became regressive. Seven months later, external
ophthalmoplegia
was disappeared and only slight anisocoria was seen. She readmitted to the hospital one year and eleven months later, because of anorexia and emaciation. She died of adenocarcinoma of the stomach without chemotherapy. The duration from onset of ocular symptoms to death was two years and one month. At postmortem examination, stomach cancer infiltrated extensively to the abdominal and pelvic viscera, but no metastasis to the nervous system or intraorbital tissues was found. There were mild to moderate atherosclerotic changes in the small-and middle-sized arteries of the kidneys, pancreas and adrenal glands corresponding to her age. Moderate atherosclerosis was found in all of the major arteries including Willis ring, siphon of the right internal carotid artery and Vertebro-basilar one.(ABSTRACT TRUNCATED AT 250 WORDS)

A 50-year-old woman developed third, fourth, and fifth cranial nerve palsies in the right associated with frontal pain in the ipsilateral side. Oral administration of prednisolone (30 mg/day) was initiated. The painful
ophthalmoplegia
improved dramatically following this treatment. Three months later, the patient developed the third, fourth, and fifth cranial palsies in the left which was contralateral to the previous episode. The patient had pain in the left frontal region. The corticosteroid therapy was again effective. Cavernous sinus and orbital venographies demonstrated a constriction of the right superior ophthalmic vein in the first and third parts, with a partial filling of the cavernous sinus. The left superior vein and cavernous sinus were normal. A left carotid arteriogram showed a slight deformity of the carotid siphon in the left. The
glucose
tolerance test demonstrated a mild diabetic pattern. Diabetic
ophthalmoplegia
can also be suspected in this case, however, the finding of a partial filling of the right cavernous sinus was indicative of Tolosa-Hunt syndrome. Therefore this case was diagnosed as Tolosa-Hunt syndrome. Alternating relapsing Tolosa-Hunt syndrome involving the third, fourth and fifth cranial nerve as seen in this case is very rare. There are many diseases which may demonstrate similar symptoms; i.e. parasellar tumor, aneurysm, diabetic
ophthalmoplegia
, multiple cranial neuropathy, etc. The pathologic process involved in Tolosa-Hunt syndrome is poorly understood and it appears that the clinical entity of this syndrome should be questioned. We believe that it is necessary to clarify the precise pathologic process involved in this syndrome and its relation with other similar syndromes exhibiting similar symptoms.

A 42-year-old woman had a 10-year history of external
ophthalmoplegia
, malabsorption resulting in chronic malnutrition, muscle atrophy and polyneuropathy. Computer tomography revealed hypodensity of her cerebral white matter. A metabolic disturbance consisted of lactic acidosis after moderate
glucose
loads with increased excretion of hydroxybutyric and fumaric acids. Post-mortem studies revealed gastrointestinal scleroderma as the morphological manifestation of her malabsorption syndrome, ocular and skeletal myopathy with ragged red fibers, peripheral neuropathy, vascular abnormalities of meningeal and peripheral nerve vessels. Biochemical examination of the liver and muscle tissues revealed a partial defect of cytochrome-c-oxidase (complex IV of the respiratory chain). This mitochondrial multisystem disorder may represent a separate entity to be classified between the spectrum of myoencephalopathies and oculo-gastrointestinal muscular dystrophy.

A 48-year-old male developed fever and sore throat while in Spain and was admitted to hospital, dehydrated, ketotic, pyrexial, and with a blood
glucose
of 35 mmol/l. Despite treatment with intravenous fluids, insulin, cephalosporin, potassium and bicarbonate he returned to Britain 7 days later, underhydrated and acidotic, though euglycaemic. His face was discoloured, there was painless nasal and maxillary swelling, oral candidiasis, and he went on to develop
ophthalmoplegia
and sudden blindness. Staphylococcus albus and mycelial fungus were isolated, the latter was identified as Mucor hiemalis, but despite treatment with amphotericin B co-ordinated with radical maxillary-facial surgery he died 31 days after the initial symptoms. Rhinocerebral mucormycosis is a recognized complication of ketoacidosis which is rarely reported in the UK. The organism invades arteries aggressively, therefore radical therapy must be started early to prevent the high mortality.

Acromegaly is caused by GH-secreting pituitary adenomas and, in rare cases, by ectopic production of GRH with resultant hypersecretion of GH. Important systemic manifestations include acral enlargement, swelling, disfigurement, glucose intolerance and diabetes, hypertension, nerve entrapment, arthropathy, and cardiac disease. Tumor-related major manifestations are visual impairment,
oculomotor paralysis
, and hypopituitarism. Morbidity is substantial, and mortality is increased. Diagnosis should be made as early as possible by measuring plasma GH after an oral
glucose
load and plasma somatomedin C levels. Assessment of a pituitary lesion is best made by CT scanning in the coronal plane. Therapy is mandatory and consists of surgical removal of the pituitary adenoma (usually by the transsphenoidal route) or of the ectopic source of GRH (carcinoids or islet cell tumors). Adjunctive radiation and/or drug therapy is often necessary if complete surgical ablation of the adenoma is not possible. Radiation therapy can be administered as conventional supervoltage x-ray treatment or in the form of heavy particle beams. Drugs effective in partially lowering GH levels are bromocriptine and (not yet released) somatostatin analogues. Long-term follow-up of treated patients is important to guard against recurrence, progression, or development of hypopituitarism.
