Muscle phosphofructokinase deficiency: abnormal polysaccharide in a case of late-onset myopathy.

A 61-year-old woman with muscle phosphofructokinase (PFK) deficiency had mild limb weakness all her life but no cramps or myoglobinuria. For 5 years the limb weakness progressed. In muscle, PFK activity was 1% of normal and glycogen concentration was elevated (2.13%). By light microscopy, a minor component of the accumulated glycogen appeared as PAS-positive, diastase-resistant inclusions in 10% of muscle fibers. The inclusions had a filamentous fine structure that resembled the abnormal long-chain glycogen of brancher enzyme deficiency. Iodine absorption spectra of both the inclusions and a diastase-resistant fraction of isolated glycogen resembled amylopectin. The abnormal polysaccharide in PFK deficiency may be related to greatly elevated concentration of muscle glucose-6-phosphate, an activator of the chain-elongating enzyme glycogen synthase.

Performance of Down syndrome and other retarded children on the Cratty Gross-Motor Test.

The Cratty Test of Gross-Motor Performance was administered to 18 Down syndrome and 18 other mentally retarded children between the ages of 7 and 14 years. Subjects were individually matched on both MA and CA. Examination of their test profiles showed that the Down syndrome children had consistently lower scores that did the matched control children, but only two of the differences were significant. The findings, therefore, provide tentative support for the notion that Down syndrome children suffer a specific deficit in some areas of motor coordination. A number of criticisms of the internal consistency of the test were discussed in terms of their theoretical and practical implications.

Minute eye movement during sleep.

The minute eye movements of 4 sleeping subjects were studied with a piezo-electric strain-gauge transducer. The frequency and amplitude of ocular microtremor activity diminished during sleep. Activity increased after auditory stimulation and with the appearance of a K complex in the EEG. The ocular microtremor activity also increased with the onset of rapid eye movement (REM). Low amplitude 'micronystagmoid' movements were observed at intervals throughout sleep. In contrast to the changes observed during sleep, ocular microtremor activity did not diminish during hypnosis. The transducer was far more sensitive than the conventional EOG recording system.

The long-distance psychiatric patient in the emergency room. Insights regarding travel and mental illness.

This paper deals with the motivational, demographic and clinical characteristics of individuals who seek psychiatric help at facilities located a great distance from their places of residence. The study identifies two subgroups within this category. The first (Intentional or Type A) group is constituted by persons who, owing to their concerns with the social stigma of mental illness, or driven by the desire for a magical solution to their problems, purposely undertake the journey to a distantly located psychiatric center. The second (Incidental or Type B) group consists of vacationers, hitch-hikers and skid-row individuals. While these "long distance patients" (LDP) did not show any differences when compared with the remainder of clinic attendance on demographic variables, distinct clinical features differentiated the two populations. Most significantly the LDP had a higher incidence of schizophrenia and alcohol related problems. The difference was entirely accounted for by the Type B subgroup ((LDP less than 0.01; Type A, NS; Type B less than 0.001). Implications of this finding have been discussed in view of the suggested relationships between travel and mental illness. Administrative problems of the LDP have been briefly commented upon.

Efficacy of bifocals in the treatment of accommodative esotropia.

We treated 84 patients with a partially refractive accommodative esotropia with bifocals. Twelve patients were able to fuse without bifocals at the end of therapy; in 19, the bifocal power could be reduced and further improvement can be expected in the future. Thirty-nine remained dependent on bifocals; and in 14, fusion had deteriorated in spite of therapy. Patients with a high AC/A ratio and those receiving supportive orthoptic treatment seemed to fare best with bifocals. In those with a low AC/A ratio, fusion tended to deteriorate because of a slowly increasing esodeviation at near fixation.

The mental health team on a burn unit: a multidisciplinary approach.

The usual methods of psychiatric consultation in a medical-surgical ICU setting were found to be inadequate to deal with the complexly interrelated issues of patients' emotional reactions to severe injury and the simultaneous stresses on the staff who care for such critically ill patients. A new approach to consultation/liaison in this setting, a multidisciplinary mental health team, is described and illustrated to demonstrate a more effective model for dealing with a patient-staff system under chronic high stress.

A comparison of the treatment of trochanteric fractures of the femur by internal fixation with a nail plate and the Ender technique.

In our experience, trochanteric fractures fixed with Ender nails achieved a degree of success similar to those treated by nail plating, but the risk of wound infection was much less with the former method. The results of 78 trochanteric fractures of the femur internally fixed with Ender nails have been analysed and compared with the results in 100 similar patients treated by nail plate fixation. The Ender method has advantages over existing operative methods, in that in our series the infection rate was zero and we found that the operation produced less shock. We consider that this method, although technically more difficult, can be used for most intertrochanteric fractures and merits further trial.
