Fibrodysplasia (myositis) ossificans progressiva (FOP) is a rare autosomal dominant disorder in which there is a progressive ectopic ossification and skeletal malformation, mainly in the connective tissue of muscle. The diagnosis is based on the clinical findings and radiological demonstration of the skeletal malformations. We report a 5 year-old female case with FOP.

The Reaction Level Scale (RLS85) is a range scored coma scale (8 levels) for the assessment of responsiveness in patients with acute brain disorders. Its feasibility in clinical practice and for research studies has been verified in a multicentre study and by comparison with other current coma scales. Range scoring and absence of pseudoscoring are its most significant advantages over the other current scales. An operative manual of the RLS85 in Portuguese is standardized in this text which also provides a selected bibliography on the subject.

An overview is presented on historical and multivariate aspects of cerebral hemometabolism. This involves a full multivariate approach, from blood pressure to cerebral metabolism. ⋯ A generic proposition is made for studies of truly normal cerebral hemometabolism in children, for subsequent clinical applications. Another proposition is made for multivariate cerebral hemometabolic monitoring, in a broad variety of circumstances of predominantly global changes in intracranial dynamics, both in animal and clinical research.

Comparative Study
[Extradural hematoma: comparative radiological study between comatose and non-comatose patients].
A series of 129 patients harbouring extradural hematomas was analysed considering the neurological state immediately before operation as the most consistent variable. Seventy eight patients were considered to be comatose (Group I) and 51 were noncomatose. ⋯ Associated intracranial lesions increased the mortality and lowered the good results in both groups. Frontal hematomas (10 cases) in the comatose group were associated with high mortality (52.6%) due to bad neurological state (Glasgow 3-5) and to isolated or multiple intracranial associated lesions (6 patients).

The diagnosis of primary intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) has become easier with the advent of modern imaging techniques. The incidence of ICH has declined, while SAH has remained relatively constant. The prognosis for both disorders remains dismal and the mortality rate is substantially higher than that observed with ischemic stroke. ⋯ For SAH, calcium channel blockers may reduce cerebral ischemic complications related to vasospasm, but effective medical therapy to prevent rebleeding has not been established. Early surgery after SAH should be considered in clinically stable patients. Many challenges remain regarding the prevention and treatment of both these cerebral hemorrhage subtypes.
