Case reports (1970--1977) of thirty-five pregnant women with acute appendicitis were reviewed. Eighty-eight per cent had symptoms less than 24 hours and were operated on within 12 hours. No maternal or fetal loss occurred. Morbidity and mortality should be minimal if, when appendicitis is suspected in a pregnant woman, immediate operation is performed.
The protein requirement and the efficiency of protein used were studied in young and old adult human subjects. Protein intake levels (N X 6.25) of 0.4, 0.8, and 1.6 g/kg body weight per day from a combination wheat-soy-milk mixture were fed. Caloric intake was held constant at 40 kcal/kg body weight per day throughout the 11-day study of each dietary period. No significant differences were observed in their protein requirement, efficiency of protein use or the ability to adapt to changes of protein intake levels. Protein digestibility was not impaired in the aged. It is concluded that the protein requirement and the efficiency of protein use are not affected by the aging process.

We observed 36 tumors of the cranial vault in children (11 epidermoid and dermoid cysts, 3 meningiomas, 3 malignant tumors, 11 vascular tumors, 6 eosinophilic granulomas, 2 osteomas). The common clinical finding enabling us to include all 36 tumors in this study is a large tumefaction of the cranial vault, without our being able to determine its anatomical starting point or histological nature. These observations are described according to whether they have a bony, dural or cutaneous origin, differentiating tumors of embryological origin. In the majority of cases, internal and external carotid angiography was performed to help surgery, which remains the only cure.
Since May 1975 was have been working in the field of C.A.T. and its application to study head injuries. We are presenting differents groups of patients studied by C.A.T. I. -- DATA OF C.A.T. IN THE CASES OF EMERGENCY AND IMMEDIATE POST-OPERATIVE FOLLOW-UP OF HEAD INJURIES A) EMERGENCY STATE As soon as the clinical state of an head injured patient was supposed to need an operation, C.A.T. was realized; so differents abnormal scanners may be observed: 1. epidural hematoma, 2. subdural hematoma, 3. intra-cerebral hematoma, 4. acute subdural hematoma or contusion. We must do some comments: -- The Emi-scanner is pre-eminent in showing the exact topography of the lesion : so, the flap is easier to realise. -- In most cases the Emi-scanner is easier to interpret than angiogram for example contusion and hematoma. We know the goods results in hematomas and the poors results in surgery of contusions. -- But the senior advantage of C.A.T. is to provide all the informations in the totality of skull content. Emi-scanner shows bilateral lesions, ipsilateral lesion. C.A.T. is pre-eminent in showing the presence of this two lesions, more accurately than senior methods of investigations, so C.A.T. permits emergency neurosurgical treatment. B) C.A.T. AND FOLLOW-UP Repeated studies at post-intervals can be accomplished without risk to the patient, thus making follow-up simpler and more effective to the neurosurgical attitude. C) POST-OPERATIVE CONTROL AND C.A.T. Post-operative complications are always hard to diagnosis. C.A.T. is painless, quick and safe, and easier to interpret than an angiogram. II -- SEQUELLAE STADE AND C.A.T. In this field certains advantages of C.A.T. are immediatly apparents. In most cases the C.A.T. is the best screening method. Patients carried out are: -- psychiatric troubles, -- post-traumatic epilepsy. The results are not reliable. There is no anatomical-clinical relation in most cases. Differents pictures are observed: -- asymetrical ventricle enlargment, -- global ventricule enlargment, -- partial cerebral atrophy. III -- DISCUSSION 1. We are at the beginning of our study. 2. This not always possible to obtain a C.A.T. in emergency for a head injury, especialy at night. 3. Patients investigated following head trauma are among the most difficult to study with C.A.T. These invididuals send to be restless and uncooperative. Numerous artefacts produced by patient motion may lead to erroneous negative or positive diagnosis, so general anesthesia is often helpful. It is hoped that as a more rapid scanners become available this problem will be obviated. The C.A.T. alone is not capable, to provide all the necessary date concerning head injury. The C.A.T. is, however, re-adjusting our total investigation (E.E.G., angiograms) philosophy and practice rather than replacing the standard neuroradiological technique, except, may be, with epidural hematoma.

The authors present a case of intra-osseous meningioma in a 10 years old boy, located on the level of the vertex in the fronto-interparietal region, with the shape of a hand mass, painless, free from all neurological, ophtalmological and angiographic signs. The x-rays examination permit a diagnosis of an osteoma of the cranial vault. The surgery enables the exeresis of a large tumor of the vault 3 cm thick, without any attachment to the dura-matter. The histological examination reveals that it is, in fact, an intra-osseous meningioma. From this observation the authors carried out a review of all litterature in this field, only 12 observations are found again, and none of them deal with children. These intra-osseous meningioma develop from Pacchioni granulations included in the diploic region. They bring about handly any clinical signs and the x-rays findings do not enable us to put forward or suggest the diagnostic of intra-osseous meningioma.
