Transorbital penetrating brain injury caused by a toy arrow: a case report.

A case of a 9-year-old boy with a transorbital toy-arrow injury to the brain is presented. At admission he was in coma (Glasgow Coma Scale of 6) with right hemiparesis and had a completely prolapsed left eye. Computerized tomography revealed intracranial haemorrhage and fracture of the orbital wall, which were treated conservatively. His left eye was enucleated due to massive injury. At the 6-month check-up the boy still show neurological signs of latent right hemiparesis. Disturbances, mostly cognitive, were noted on his psychological tests. A survey of the literature reveals no report of this nature in the paediatric age group. The necessity of continuous monitoring of new environmental risks as they occur, and the requirement for the prevention of recreational brain injuries in children, is stressed.

[Epilepsy with centrotemporal (Rolandic) spikes. A peculiar seizure disorder of childhood].

The study presents the results of a long term investigation of 60 epileptic children with Rolandic (centrotemporal) spikes in EEG. The results could be summarized as follows: the Rolandic epilepsy is relatively frequent entity (13.4% of the total number of epileptic children). The age span was from 3--13 years, with a peak of age incidence between the 7th and 8th year of life. More than half of children had nocturnal fits only. From the clinical point of view 60% of children had generalized crises, and the remaining 40% had partial attacks corresponding to the functional organization of the Rolandic cortical area. The evolution of the Rolandic epilepsy in childhood is favourable. More than 50% didn't have more attacks after the introduction of antiepileptic therapy, and 3/4 of them could be classified as practically cured after an long-term follow-up (criterion: an attack-free period of at least 5 years. Finally, in more than 80% of cases after three years of follow-up the spikes have disappeared from the EEG tracings which were completely normal.

[Carcinoma in situ in the urinary bladder].

In this paper we have presented seven patients with carcinoma in situ of the urinary bladder, a rare intraepithelial form of transitional cell carcinoma of the urinary bladder, described first in 1952. In all patients malignant cells were detected in urine sediment, and the diagnosis was proven histopathologicaly by random biopsies of the urinary bladder. In five patients carcinoma in situ was associated with papillary bladder tumor, while two patients had primary carcinoma in situ. We have emphasized a high rate of irritative urinary symptoms, that can lead to diagnostic mistakes. Three patients had reduced bladder capacity. In all patients a complete response was achieved after local immunotherapy or local chemotherapy. After a follow-up lasting from 23 to 61 months in one patient a recurrent carcinoma in situ was diagnosed, while six patients show no signs of recurrent disease.

[The effect of epidural analgesia in labour upon serum catecholamine levels].

The serum levels of catecholamines were determined in 26 healthy parturients. Epidural analgesia was given in 13 cases, while the remaining women were given classic parenteral analgesia and served as controls. The blood samples were taken before analgesia and after delivery and also from the clamped umbilical vein from the newborn after delivery. There was a statistically significant decrease of catecholamine levels in the epidural group and a slight increase in the control group. There were no differences among the newborns.
