The age distribution of anginose infectious mononucleosis in children was analysed retrospectively for the years 1966-85. During that period the disease became significantly more common in children of a young age and less common in older children. This shift could not be attributed either to socioeconomic conditions or to the diagnostic methods used.

Two girls, one with progressive systemic sclerosis and a second with dermatomyositis, developed calcinosis in the skin of the prepatellar area. Calcinosis was accompanied by local inflammation and skin ulceration. Oral colchicine therapy in a dosage of 1 mg per day was followed within two months by significant regression of local inflammation and healing of the skin ulcers.
Deterioration of handwriting in an 11-year-old boy over a 2 month period was found to be caused by a cerebellar astrocytoma. The clinical picture was characterised by a lack of the classic symptoms of increased intracranial pressure. The only positive neurological findings pointed to an isolated right cerebellar symptomatology expressed by mild intention tremor and decreased tone of the right hand. Progressive deterioration of handwriting can be an ominous sign and it should be known to all professionals, as a lack of awareness can cause delay in expert referral and diagnosis.
Calcified chronic subdural haematomas (SDH) and features of arrested (compensated) hydrocephalus were demonstrated by skull radiography and cranial computed tomography (CT) in two children who had no neurological deficit. Ventricular surgical drainage had been performed 8 and 11 years prior to admission and the haematomas remained subsequently undetected. The following presentation will serve to illustrate the characteristic radiological features of this entity, the issue of management, and includes a review of the literature.

Three infants, recognised as blind during the first 4 months of life, were found to be normal on neurological and ophthalmological examinations. Visual electro-diagnostic studies showed normal retinal responses, but delayed conduction velocities and impaired visually-evoked responses over the occipital cortex. After age 6 months, normal vision developed gradually and all abnormalities disappeared.

We measured serum lipids and lipoproteins in 33 epileptic children who were treated with phenobarbital, valproate, and carbamazepine. High-density lipoprotein cholesterol (HDL-c) was significantly higher in the epileptic children than in two control groups: healthy nonepileptic children, and epileptic children before starting anticonvulsant therapy. Our findings indicate that anticonvulsant drugs should be added to the list of substances that affect serum HDL-c.
