Autosomal recessive idiopathic torsion dystonia in a kindred of mixed ancestry

A family with idiopathic torsion dystonia (dystonia musculorum deformans) was seen in a peripheral clinic in the Richtersveld in the north-western Cape. This rare inherited form of neurological disease has maximal prevalence in individuals of Ashkenazi Jewish ancestry, and there is controversy regarding the exact mode of inheritance. The kindred documented in this study was of mixed ancestry (Cape Coloured), and autosomal recessive inheritance was suggested by the finding of affected male and female siblings born to normal parents in an isolated inbred community.     

Intracranial circulation: pulse-sequence considerations in three- dimensional (volume) MR angiography

The technique and feasibility of magnetic resonance (MR) angiography of intracranial vessels were studied in 35 healthy volunteers. Variations in image orientation, repetition time (TR), and flip angle were evaluated to determine their effects on flow-related enhancement. Gradient modifications--including echo time (TE), motion compensation, bandwidth, and field of view--were also studied in an effort to reduce motion-induced phase shifts. Results indicated that a FISP (fast imaging with steady precession) sequence with a TR of 50 msec, TE of 15 msec, velocity compensation in the read and section-select directions, acceleration compensation in the read direction, anisotropic volume, and a 1.25-mm partition thickness produced three-dimensional angiographic MR images that were accurate and reproducible in the depiction of the major intracranial vessels. Difficulties with field of view, persistent signal void secondary to higher-order motion, and spatial resolution remain major problems requiring additional study.     

Giving up driving in Alzheimer's disease—an integrative therapeutic approach

For patients with Alzheimer's disease (AD), a recommendation to stop operating a motor vehicle can be a serious event complicated by a loss of self-esteem and personal dignity. Patients are often reluctant to give up an activity so essential, both practically and symbolically, to independent living. We describe here a patient with moderately progressed AD who lacked insight of his need to cease driving. Through an integrative treatment approach, combining behavioral and psychodynamic modalities, we helped him to formulate effective ways of coping with his loss of access to independent transportation. We favor a psychotherapeutic strategy that combines behavioral and managerial measures with dynamic patient interaction, thereby developing the patient's insight of the need to give up driving while fostering his sense of autonomy.     

Paediatric dacryocystorhinostomy

Of 258 cases of dacryocystorhinostomy performed on children in the period September 1981 to September 1991, 130 were for simple, unresolved congenital nasolacrimal duct obstruction. Other indications for surgery included punctal agenesis, lacrimal fistula, post-traumatic and post-inflammatory canalicular obstruction. Of 177 children without canalicular pathology, 171 (96%) were relieved of symptoms with one operation, without canalicular intubation. Of 81 cases with canalicular disease, 55 of 70 (79%) who underwent DCR plus canalicular intubation, and 10 of 11 who underwent DCR plus Lester-Jones tube, were substantially improved with one operation. No child required peroperative or postoperative blood transfusion. Dacryocystorhinostomy in childhood, in experienced surgical hands, is a safe procedure, achieving relief of symptoms in most cases, particularly in the absence of canalicular disease.
