Long-term survival in children under 3 years of age with low-grade astrocytoma

Objective The purpose of this study is to analyze clinical aspects and disease-free survival (DFS) in children less than 3 years of age diagnosed with low-grade astrocytoma. Methods In a period of 24 years (1980–2004), a total of 43 (5.4%) children were registered with these characteristics. Twenty-three patients had pilocytic astrocytoma, 18 diffused, and 2 mixed. Thirty-one (72.1%) children had incomplete surgical tumor resection and 12 (27.9%) had a complete tumor resection. Twelve (27.9%) patients had cranial radiotherapy and 17 (39.5%) received chemotherapy. Overall survival was recorded in 23 (53%). DFS was 50% at 250 months of follow-up for the whole group. DFS for the supratentorial group was 60% at 250 months, whereas, for the infratentorial, it was 22% at 120 months (p = 0.008). Conclusion The only favorable prognostic pattern was the supratentorial presentation. Radiotherapy and chemotherapy did not alter the outcome.     

Foetal radiation dose in radiotherapy for breast cancer

Management of breast cancer during pregnancy is complicated by the high risks of abortion and foetal malformation from the use of radio therapy and chemotherapy. A case of breast cancer during pregnancy, treated with radiotherapy, and the estimated foetal dose is reported.     

Transurethral resection of a bladder tumor in pregnancy: A report of 2 cases

Carcinoma of the urinary bladder presenting during pregnancy is rare. We report two such cases presenting with gross hematuria, both of which were managed by transurethral electroresection of the tumor; there was no adverse effect on the pregnancies. Transurethral resection thus appears to be the procedure of choice in the management of this condition, and carries minimal morbidity even when performed during pregnancy. EDITORIAL COMMENT: As these authors point out, bladder tumors are rare in pregnancy and frequently present as gross hematuria that is mistaken for vaginal bleeding due to the pregnancy. Ultrasound is very helpful in distinguishing the causes of bleeding, and will show the bladder filled with clots and frequently the tumor as well. Standard transurethral resection is effective when performed during pregnancy, bearing in mind the need to heed to the anesthetic risks inherent in any operative procedure during pregnancy.

Initial cranial CT scan for the assessment of prognosis in head injury

Summary A total of 208 multiple trauma patients with head injury (HI) were investigated who had been treated in the period from 1990 to 1995. The average age was 35.2 ± 17.7 years; the injury severity according to ISS was 30.2 ± 8.6 points; 20.5 % died as a result of the HI; the mortality of all patients was 26.5 %. The Glasgow Coma Scale (GCS) was determined at an average of 22 min after trauma (8.0 ± 4.3 points) at the scene of accident. The patients were classified according to GCS into minor HI (group 1: 14–15 points), moderate HI (group 2: 9–13 points) and severe HI (group 3: 3–8 points). Patient outcome was assessed by the Glasgow Outcome Scale (GOS) and was classified as good (GOS 4 and 5) and poor (GOS 1, 2 and 3) outcome. At the latest, 2 h after trauma, a CT scan of the head (CCT) was done. The HI groups are compared regarding frequency of types of injury. In all HI groups the fractures of the bony face occurred at the same frequency (36.0–38.9 %). The frequency of calotte fractures (Kal-Fx) increased from group 1 (8.0 %) to 2 (19.2 %) and 3 (25.6 %); fractures of the skull base significantly differed between group 1 (16.0 %), 2 (7.8 %) and 3 (33.4 %). Epidural hemorrhage (EDB) appeared only in group 2 (7.8 %) and 3 (6.7); subdural hemorrhage was found in group 1 (2.7 %), 2 (7.8 %) and 3 (10.0 %). Subarachnoid hemorrhage (SAB) was significantly more frequently seen, dependent on HI severity, in group 3 (26.7 %) compared to group 2 (11.7 %) and 1 (8.0 %). Intracerebral contusion (ICK) significantly increased from group 1 (12.0 %) to 2 (27.3) and 3 (45.6 %). Brain swelling (BS) also significantly increased from group 1 (8.0 %) to 2 (19.5 %) and 3 (49.0 %) and lesions of ventricles (VL) from group 1 (2.7 %) to 2 (11.7 %) and 3 (20.0 %). Midline shift (13.4 %) and signs of herniation (4.5 %) only occurred in group 3. The analysis of correlation/regression and receiver operating characteristics was able to predict 79 % of patients' outcome accurately using GCS (r 0.54; P < 0.0001) alone, using CCT (r 0.65; P < 0.0001) 87 % were correctly predicted with significant variables Cal-Fx, EDB, SAB and BS. CCT with GCS (r 0.74; P < 0.0001) were able to predict 88 % accurately with significant variables Cal-Fx, EDB, BS and GCS. The combination of CCT with GCS, age and ISS (r 0.78; P < 0.0001) was able to predict only 87 % correctly, although the r value was the highest; significant variables were Kal-Fx, EDB, BS, VL, GCS, age and ISS.      

Practical selection criteria for unenhanced cranial CT in patients with acute headache

We studied clinical predictors of cranial computed tomography (CT) abnormalities in patients with acute or acutely worsened headache. Data were collected from chart review of 333 consecutive patients presenting to an emergency department and who were clinically selected for cranial CT. Patients with a positive neurologic examination were at 10.7 times greater risk for a positive CT than the rest of the sample (p<1.5 – 10⁻¹⁰). Using only neurologic examination to select patients for CT would have missed 30.3% of the positive scans. The amnesia, depressed sensorium, and hypertension variables had CT yields approximating 10% or greater even in the presence of a negative neurologic examination. Together with a positive neurologic examination, these variables detected 87.9% of the patients in this sample with positive scans; their absence had a negative predictive value of 98.0%. Of the four patients with positive scans who would have been missed using this strategy, one was discharged directly from the emergency department anyway and the other three developed positive neurologic examinations within 24 hours. One died of causes unrelated to the intracranial pathology. Positive neurologic examination, hypertension, history of amnesia, or a depressed sensorium provide reasonable initial guidelines to select for CT patients with an acute headache.     

Arteriovenous malformations that rupture during pregnancy: a management dilemma

Summary Intracranial haemorrhage due to rupture of an arteriovenous malformation (AVM) during pregnancy is a rare but serious condition that warrants prompt recognition. Once the diagnosis is made, the management is primarily based on neurosurgical rather than obstetric considerations. Due to its rarity, no definitive guidelines exist, and the best time to perform elective surgery (i.e., at presentation or at completion of the pregnancy) is ill-defined. This report describes three patients recently treated at our institution who had AVMs that ruptured during pregnancy. These cases well summarize the difficulties encountered in treating such patients. The diagnostic as well as the therapeutic implications of this condition are discussed.
