The three Community Hospital-based Stroke Programs collected data on 4132 stroke patients admitted to acute care hospitals during 1979 and 1980. White female stroke patients were older than the white male, nonwhite female and nonwhite male stroke patients. Nearly one-fourth (23%) of stroke patients were employed at the time of the event. Most (77%) of the patients were hospitalized for first stroke episodes. Eighty-three percent of the patients had at least one of the four major risk factors for stroke, namely, hypertension, diabetes, transient ischemic attacks and cardiac disease. Half (49%) of the patients were alert at the time of admission. The three diagnostic categories included infarction (60%), stroke not otherwise specified (30%) and hemorrhage (10%). Fourteen days was the median length of hospitalization; 50% of the stroke patients were discharged to a home setting, 31% were institutionalized and 19% died while in the hospital. The mean Barthel Index score for 2400 patients at the time of discharge was 61.8 (normal is 100). Of those patients who were working at the time of the stroke, 22% returned to work. In comparison to the patients in the National Survey of Stroke, patients in this Study were less severe at the time of admission (49% of patients in the National Survey of Stroke were stuporous or comatose compared to 21% of the patients in the current Study). The inhospital fatality was 30.7% in the National Survey of Stroke, and 19.7% in the current Study.

Four patients with diabetes mellitus and no underlying clinical pulmonary disease were found to have extensive unilateral mucous occlusion of a major central bronchus. None of the patients had significant auscultatory findings suggestive of pulmonary secretions, and chest roentgenographic films were normal. Arterial blood gas evaluation failed to reveal the usual hypocapnia during ketoacidosis, thus prompting bronchoscopic examination or deep airway suctioning. These interventions disclosed and resolved the mucous obstruction of the compromised bronchus. Antibiotic therapy, based upon bronchial secretion Gram stain and culture, was successfully instituted in all patients. Lethargy and autonomic neuropathy are proposed as contributing factors responsible for occult mucous plugging in diabetic patients in ketoacidosis. The absence of hypocapnia in this setting may be the only clue to silent mucous plugging of airways.

Pseudobulbar mutism is rarely attributed to bilateral discrete posterior limb internal capsule-medial globus pallidus infarction. Few cases of bilateral anterior choroidal (AchA) artery territory infarction have been reported. We present 8 patients with ischaemic stroke in this location and vascular distribution who have a characterizable syndrome. All had the abrupt onset of inability to speak, swallow or phonate, accompanied by varying degrees of facial diplegia, hemiparesis, hemisensory loss, lethargy, neglect and change in affect. The appearance of clinical signs depends upon the presence of a new infarct contralateral to an older lesion in mirror position. The pathogenesis and progression of neurological deficit appears to be intimately related to hypertension. The role of intrinsic intracranial vascular pathology related to diabetes mellitus, embolism of cardiac origin and atherosclerosis is currently undefined. The prognosis for recovery is poor. Half of our patients died within a year of onset of symptoms. Capsular pseudobulbar mutism is recognized by the abrupt appearance of neurological deficit consistent with internal capsular pathology and is confirmed by CT scan or MRI.

1. At 30 weeks of age, homozygote diabetic C57 BL KsJ (db/db) mice were grossly obese, lethargic and displayed moderate hair loss relative to heterozygote control C 57 BL KsJ (db/+) mice. 2. In diabetic mice, compared to control, the total body weights, liver weight: body weight ratios, and blood glucose levels were increased 2.3 fold, 20% and 3.1 fold, respectively. 3. Analysis of plasma membranes isolated from control and diabetic mouse liver established that comparable purity levels were achieved since relative specific activities of the plasma membrane markers 5'-nucleotidase and gamma-glutamyltranspeptidase were similar: 10.2 and 11.4 fold with respect to 5'-nucleotidase in control and diabetic states respectively; and 8.0 and 8.3 fold with respect to gamma-glutamyltranspeptidase in control and diabetic states respectively. 4. A select effect of diabetes on gamma-glutamyltranspepetidase, however, was observed. The activity of this enzyme was found to be reduced 16% in diabetic liver compared to control liver. 5. Assessment of [3H]prazosin and [3H]dihydrolalprenolol binding to mouse liver plasma membranes indicated that although there was no difference in beta-adrenergic receptor binding in control and diabetic states, alpha 1-adrenergic receptor binding was found to be reduced 43% in diabetic mouse liver plasma membranes. 6. Scatchard analyses of kinetic studies indicate that the reduction is a reflection of decreases in alpha 1-adrenergic receptor numbers with no change in alpha 1 receptor affinity in the diabetic state: since for diabetic and control liver plasma membranes, Kd values were 3.41 +/- 0.02 nM and 3.40 +/- 0.01 nM respectively; and Bmax were 650.12 +/- 16.44 fmol mg-1 and 380.76 +/- 12.92 fmol mg-1, respectively.

We report a case of symptomatic essential fatty acid deficiency (EFAD) occurring in a free-living individual with type I diabetes mellitus who was voluntarily following a high-carbohydrate, fat-restricted diet. The patient was 43 yr old with type I diabetes for 18 yr and no chronic complications. His self-imposed diet excluded all red meats, fats, and oils. After several months of this diet, the patient developed lethargy and a pruritic, diffuse, scaly, and erythematous rash. Biochemical studies revealed a mildly elevated SGOT and abnormally low levels of linoleic, linolenic, and arachidonic fatty acids. Treatment with linoleic acid supplementation in his diet improved the rash, normalized SGOT, and corrected the fatty acid profile. We conclude that EFAD may occur in a free-living individual after consuming a very-low-fat diet.

Thirteen cats with diabetes mellitus were evaluated. Clinical signs included polydipsia, polyuria, polyphagia, lethargy, and weight loss. Results of physical examination included obesity, hepatomegaly, mild seborrhea sicca, muscle wasting, and dehydration. One cat walked plantigrade and was suspected of having a diabetic neuropathy. Persistent hyperglycemia, glucosuria, high liver enzyme activities, hypercholesterolemia, hyperproteinemia, and low electrolyte concentrations were the common laboratory findings. In 3 cats diabetes mellitus developed after megestrol acetate therapy; 2 of these cats required only temporary insulin treatment. In a 3rd cat, which had no history of receiving diabetogenic drug therapy, remission of diabetes mellitus also was observed. Serum insulin and plasma glucose concentrations were determined in 6 cats after administration of an intermediate-acting insulin (isophane insulin) and in 3 cats after administration of a long-acting insulin (protamine zinc insulin). The insulin concentration peaked 2 to 6 hours after the injection of intermediate-acting insulin and 6 to 12 hours after the injection of long-acting insulin. The lowest glucose concentration was recorded 4 to 8 hours after injection of intermediate-acting insulin, and 6 to 12 hours after injection of long-acting insulin. It was concluded that, although insulin therapy must be adjusted to the individual, the diabetic cat usually requires twice-daily administration of isophane insulin; however, the protamine zinc insulin can be given once daily for satisfactory control.

A patient with a history of diabetes mellitus and congestive heart failure was taking furosemide and metolazone as diuretics. Diabetic ketoacidosis developed, and the patient became lethargic and confused. Initial biochemical determinations showed an alkalemic pH, serum and urine ketones with an anion gap, and hyperventilation. The hyperventilation was appropriate for the degree of ketoacidosis but it was grossly inappropriate for the alkalemia. This could be explained by a direct effect of ketones on the respiratory center or a sudden increase in hydrogen ion concentration superimposed on previously chronic alkalemic pH due to the potent combination of furosemide and metolazone.

To evaluate the efficacy of low-dose insulin therapy in cases of severe diabetic ketoacidosis (DKA), we examined admission clinical and biochemical parameters and responses to therapy in 48 diabetic patients who presented with DKA and were randomized to receive either high- or low-dose insulin. There were no differences in the initial clinical and biochemical parameters of the patients, regardless of assignment to low or high dose; however, a subgroup of 13 patients who were classified as severe DKA (based on their presentation in a comatose or stuporous state) had, as expected, more marked clinical and biochemical abnormalities than their alert cohorts. The responses to therapy (rate of glucose decrement and control of acidosis) were comparable in the high-dose and low-dose groups of comatose/stuporous patients and were not significantly different from the noncomatose cohorts. These data indicate that low-dose insulin therapy in severely ill comatose patients is as effective as high-dose.

The case of a 26 year old woman who had been taking tranexamic acid to prevent uterine bleeding due to an IUD and who died from thrombosis of the left internal carotid artery is reported. The patient's father had died at age 54 of myocardial infarction. Otherwise the family history was entirely negative for thromboembolic disease. The patient was a mild smoker. She had been previously healthy and in particular, she was not affected with hypertension, diabetes, or dyslipidemia. She had carried to term 2 uncomplicated pregnancies. 40 days prior to hospital admission her gynecologist had inserted an IUD. The insertion of the IUD was followed by persistent uterine bleeding, and for this reason she began treatment with tranexamic acid (1.5 g/daily). Uterine bleeding persisted despite this treatment, and the IUD was removed. Because of persistence of a mild uterine bleeding, tranexamic acid was continued. 2 hours before admission the patient suddenly presented a left sided hemiparesis with disarthria and vomiting. On admission she was stuporous. The left side of her face drooped and the strength of the left arm and leg was markedly decreased. Both arm and leg reflexes were symmetrical. Her blood pressure was 110/70. An electroencephalogram on arrival confirmed a right sided cerebral lesion. Subsequently the patient's condition deteriorated rapidly. She developed a full left hemiplegia and became deeply comatose. A CAT scan performed 4 hours after admission showed no abnormalities. A CAT scan performed 3 days after admission showed a large cerebral infarction involving nearly the whole right cerebral hemisphere. The patient's condition remained essentially unchanged until she died 6 days after admission. Permission for autopsy was refused. Antifibrinolytic drugs competitively inhibit plasminogen activators and noncompetitively plasmin. Thromboembolic complications after the administration of antifibrinolytic drugs have long been recognized. The use of IUDs is often associated with troublesome uterine bleeding and particularly excessive menstrual bleeding. To avoid these complaints, antifibrinolytic drugs are increasingly used.

Haemochromatosis is one of the most common inborn errors of metabolism. In prospective epidemiological studies the frequency of haemochromatosis is 0.0037 (76/20333 subjects) for homozygotes which corresponds to a gene frequency of 0.061 and a frequency of heterozygotes of 0.115. Abnormality in liver function tests, weakness and lethargy, skin hyperpigmentation, diabetes mellitus, arthralgia, impotence and ECG abnormalities are the most frequent findings and symptoms at diagnosis. In recent years about 50% of patients were detected without having liver cirrhosis and 20% of patients did not have any symptoms and pathology except iron overload. Survival analyses in long-term studies showed that in the absence of cirrhosis and diabetes, iron removal by phlebotomy therapy prevents further tissue damage and guarantees a normal life expectancy. Patients with massive and long-lasting iron overload had a worse prognosis than those with less severe iron excess. Iron removal in general ameliorated liver disease, weakness and cardiac abnormalities, and also prevented the progression of endocrine alterations. Therapy, however, did not influence insulin-dependent diabetes. Most deaths in patients with hereditary haemochromatosis were caused by liver cancers which often occurred many years after complete iron removal. In patients with haemochromatosis, liver cirrhosis, cardiomyopathy, and diabetes mellitus are also significantly more frequent causes of deaths when compared with the general population. Further strategies have to evaluate the design of screening programmes in order to diagnose more patients in the precirrhotic and asymptomatic stage.
